Question

Write an equation in slope-intercept form for the line that has a slope of 2 and passes through the point (3,13) .

Answer 1

y = 2x + 7

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 (3, 13) into the partial equation

13 = 6 + c ⇒ c = 13 - 6 = 7

y = 2x + 7 ← equation of line
