Question

Find the equation of the line passing through the given points. Express the equation in slope-intercept form. (5, 5) and (–2, –2) *

Answer 1

slope = m = 7/7 = 1 = change in y values divided by change in x values

then plug that and either point into the point slope formula

y-h = m(x-k) where m=1 and (k,h) = 5,5)

y-5 = x-5

y = x

slope = 1, y intercept = 0

You could have seen that from the beginning, as for each point x=y, 5=5, and -2 = -2
