Question

The point (21,32) os on a line with slope 1.5. Find the equation of the line

Answer 1

Answer : y = 1.5x + 18

Step-by-step explanation :

First, write the equation in terms of y, x, and your constant’s variable. For my constant’s variable, I chose “A”. You’ll need to find out what “A” is to find out your equation.

Y = 1.5x + A

Plug in your x and y values

32 = 1.5(21) + A

Simplify

32 = 14 + A

-14 -14

18 = A

Plug A into your equation

Y = 1.5x + 18

Plug the X and Y back in, and it will come out as 32 = 32
