Question

What is the equation of the line that passes through the point (-2, 0) and has

a
slope of
2?

Answer 1

y = 2x + 4

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (- 2, 0 ) into the partial equation

0 = - 4 + c ⇒ c = 0 + 4 = 4

y = 2x + 4 ← equation of line
