Question

Find the equation of a line that passes through the point (5,2) and has a gradient of -3.

Leave your answer in the form
y
=
m
x
+
c

Answer 1

Explanation:

So far, what you are given is y= -3x + b

So the point is used to define b

x = 5

y = 2

2 = 5*-3 + b

2 = -15 + b Add 15 to both sides

2 + 15 = b

b = 17

Answer

y = -3x + 17
