Question

Write an equation in slope-intercept form given the information about each line.
10. slope = 4, goes through the point (3, 10)

Answer 1

Answer:

y = 4x - 2

Step-by-step 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 , then

y = 4x + c ← is the partial equation

To find c substitute (3, 10) into the partial equation

10 = 12 + c ⇒ c = 10 - 12 = - 2

y = 4x - 2 ← equation of line
