Question

Write an equation of the line, in point-slope form, that passes through the two given points.

points: (–2, 15), (9, –18)

Answer 1

Y - 15 = -3 (X + 2)

Explanation:

Answer 2

Step 1 ) finding the slope m:
m = 15+18/-2-9
m = 33/-11
m = -3

Point slope form is :
(Y-y1) = m (X - x1)
taking (-2,15) as a point and substituting the values:
Y - 15 = -3 (X + 2)
Enjoy!
