What is the slope of Y − 4x − 3?
What is the slope of Y − 4x − 3?
The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the slope is 4 .
What type of function is y 4x 3?
y = 4x + 3 is in what is called “slope-intercept” form or “y=mx+b” form which is the easiest form for graphing. The “3” is called the “y-intercept” and is where the line crosses the y axis. So, go to the “origin” (0,0) and go up three on the vertical line.
What is the Y intercept of y =- 4x 3?
The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the y-intercept is −3 .
What are the slope and y intercept of Y 3?
The equation of a horizontal line at y=3 , hence: The slope is zero. The y-intercept is 3 .
What points are on the graph of the line 2x 4y 20?
Answer: The point (10-2y, y) for any real number y, represents any point on the given line. Divide both sides by 2. So, (10-2y, y) gives us all points on the graph of the line 2x + 4y = 20.
How do you find the inequality of a graph?
There are three steps:
- Rearrange the equation so “y” is on the left and everything else on the right.
- Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
- Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y< or y≤).
What does a dashed line mean?
“Dashed line” means a line made up of short strokes with breaks in between.
Is less than shade above or below?
Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line. For a vertical line, larger solutions are to the right and smaller solutions are to the left.
Is less than dotted line?
If the inequality symbol is greater than or less than, then you will use a dotted boundary line. If the inequality symbol is greater than or equal to or less than or equal to, then you will use a solid line to indicate that the solutions are included on the boundary line.
