Question

A line passes through point (-4,6) and has a slope of -3. What is this equation in slope intercept form?

Answer 1

Answer:

y = - 3x - 6

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 = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (- 4, 6) into the partial equation

6 = 12 + c ⇒ c = 6 - 12 = - 6

y = - 3x - 6 ← equation of line
