Answer:
x= -5
Step-by-step explanation:
Add 5 to both sides
-3x -5+5 = 10 +5
-3x = 15
Divide both sides by -3.
-3x/-3= 15/-3
x= -5
Answer:
402
Step-by-step explanation:
No number is shown with an underlined digit.
Only the number 402 has 2 in it that is in the units place. That digit has a value of 2.
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.
