What is the slope of y =- 5x 3?
What is the slope of y =- 5x 3?
Using the slope-intercept form, the slope is 5 .
Is Y 5x − 3 a linear function?
This form is called the standard form of a linear equation. Example 1: Determine whether the equation y = 5x – 3 is linear or not….
| x | y = 5x – 3 | (x, y) |
|---|---|---|
| -1 | y = 5(-1) – 3 = -8 | (-1, -8) |
| 0 | y = 5(0) – 3 = -3 | (0, -3) |
| 1 | y = 5(1) – 3 = 2 | (1, 2) |
What is the domain of Y 5x 3?
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. Use the graph to find the range.
Are inequalities functions?
Equations, inequalities, relations and identities are all examples of comparisons of functions.
How do you plot an inequality?
How to Graph a Linear Inequality
- 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 is an example of a compound inequality?
For example, x > 6 or x < 2. The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. Since this compound inequality is an or statement, it includes all of the numbers in each of the solutions, which in this case is all the numbers on the number line.
What does and mean in inequalities?
A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time. It is the overlap or intersection of the solution sets for the individual statements.
What is a real life example of an inequality?
| Situation | Mathematical Inequality |
|---|---|
| Speed limit | Legal speed on the highway ≤ 65 miles per hour |
| Credit card | Monthly payment ≥ 10% of your balance in that billing cycle |
| Text messaging | Allowable number of text messages per month ≤ 250 |
| Travel time | Time needed to walk from home to school ≥ 18 minutes |
