3? i think so i don’t know if it’s right
Answer:
<h2>a) |-13 - (-4)|</h2>
Step-by-step explanation:
The formula of a distance between two points (numbers) A and B on the number line:
d = |B - A| = |A - B|
We have A = -13 and B = -4. Substitute:
d = |-13 - (-4)|
The y-intercept (where x = 0) of the equation is at -20.
For every 60 the x runs, the y falls by -10. Use rise over run to determine the slope of the equation.

Slope-intercept form is determined by the following equation:

m is your slope, and b is your y-intercept.
Plug the slope and y-intercept into the equation.
Answer:
x = 23
Step-by-step explanation:
3x + 3 + x + 85 = 180
4x + 88 = 180
4x = 92
x = 23
