What is the Y-intercept of 3x 4y 24?
What is the Y-intercept of 3x 4y 24?
Explanation: The y -intercept is when x is equal to zero, so let’s just plug zero into our equation for x . Dividing both sides by −4 , we find that the y -intercept of the line occurs at (0,−6) .
What is the slope and y-intercept of 14x 4y 24?
The standard slope-intercept formula is y = mx + b, where m is the slope and b is the y-intercept. In that case, the slope would be 3.5 and the y-intercept would be 6.
What is the slope of 6x 2y 24?
Using the slope-intercept form, the slope is 3 .
What is the Y-intercept of y =- 2x?
Using the slope-intercept form, the y-intercept is 0 .
What is the Y-intercept of y =- 3?
The Y-Intercept of a line is the point where a line’s graph intersects (crosses) the Y-axis. A y-intercept of 3 means that a line’s graph intersects the Y-axis at the point (0, 3).
What is the slope of the line represented by 2x 7y 6?
Using the slope-intercept form, the slope is 27 .
What is the slope of the line y 4?
zero
What is the Y-intercept of y =- 3 7x?
The slope is 37 and intercept on y axis is 0 .
What is the slope of y =- 3 7?
Using the slope-intercept form, the slope is 0 .
What is the slope of the line y =- 3x 2?
1 Answer. The slope is 3 and the y-intercept is 2 or (0, 2).
How do you find slope given two points?
There are three steps in calculating the slope of a straight line when you are not given its equation.
- Step One: Identify two points on the line.
- Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
- Step Three: Use the slope equation to calculate slope.
What is the slope between the points?
The slope between two points is calculated by finding the change in y-values and dividing by the change in x-values. For example, the slope between the points (7, -15) and (-8, 22) can be computed as follows: The difference in the y-values is -15-22 = -37.
What does point slope form look like?
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Do parallel lines have the same slope?
In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other. Here is a quick review of the slope/intercept form of a line.
Why parallel lines have the same slope?
Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel.
How do you determine if two lines are parallel?
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
How do you find parallel lines?
Parallel Lines Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
Which equation represents the line that is parallel to 3x 4y 7?
Any line parallel to 3x-4y=7 will have an equation of the form 3x-4y=c for some constant c. To find the value of the constant for the line that passe through the point (-4,-2), substitute x=-4 and y=-2 in the equation and solve. The equation is 3x-4y = -4 — the second answer choice.
