Question

Write the equation of the line which has a slope of -5 and passes through (-4,4). Write the answer in slope-intercept

Answer 1

y = - 5x - 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 = - 5, then

y = - 5x + c ← is the partial equation

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

4 = 20 + c ⇒ c = 4 - 20 = - 16

y = - 5x - 16 ← equation of line
