Question

What is the equation of the line that passes through the points (-2, 3) and (2, 7)?

x - y = -1

x - y = -2

x - y = - 5

x - y = - 6

Answer 1

x - y = - 5

Answer 2

Find the slope first

Slope = Rise/ Run

Slope = y1-y2 / x1-x2

(-2,3) - > x1 = -2, y1 = 3

(2,7) -> x2 = 2, y2 = 7

Slope = (3-7)/(-2-2)
Slope = -4 / -4
Slope = 1

Then find the y intercept

y = mx + b

I will use (2,7)

7 = 1(2) + b
b = 7- 2 = 5

Therefore,

y = x + 5

y - x = 5
or
x - y = -5 (This is the answer )

Answer 3

Thank you soo much ♥

Answer 4

yw .. ^.^

Answer 5

yeah x-y=-5 only

Answer 6

well here it was much easier than that you only had to replace (-2,3) in the equations and you will notice that it is true only for x-y=-5
