Question

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

Answer 1

first you need to find the slope, do you know how to

Answer 2

yes y1 + y2 then what

Answer 3

Answer 4

m = y2 - y1 / x2 - x1) is the formula to find the slope.
set 1 (-2,3)....set 2 (2,7)
lets sub in...
m = (7 - 3)/(2 - (-2)
m = 4/4 = 1

now use the point slope formula : y - y1 = m(x - x1)
I am using points (2,7)....you could also use (-2,3)...either one will work
slope (m) = 1
y - y1 = m(x - x1)
y - 7 = 1(x - 2)
y - 7 = x - 2
y = x -2 +7
y = x + 5 <-- this is your equation
