Find the equation of the line passing through the points (7, 20) and (-2, 11).

y = x + 13

Step-by-step explanation:

1. Use the coordinates to find the slope. (y2-y1)÷(x2-x1) = slope. Substitute values. (11-20)÷(-2-7)= (-9)÷(-9)=1

y=1x+b

2. Substitute coordinates to find b (y-intercept). Let's use (7,20). 20=7+b. b=13

3. Put it all together.

y=x+13

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

good luck on your studies! : )
