Question

write an equation in slope-intercept form for the line that jas a alope of 12 and passes through the point (3,20)

Answer 1

y = 12x - 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 = 12, hence

y = 12x + c ← is the partial equation

To find c substitute (3, 20) into the partial equation

20 = 36 + c ⇒ c = 20 - 36 = - 16

y = 12x - 16 ← equation of line in slope- intercept form
