Question

(5,4), m

= 4
What is the equation of the line that passes the given point and has the given slope?

Answer 1

y = 4x - 16

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 = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (5, 4 ) into the partial equation

4 = 20 + c ⇒ c = 4 - 20 = - 16

y = 4x - 16 ← is the equation of the line
