Question

A line has a slope of -2 and passes through the point (-3, 8). Write its equation in slope-

intercept form.
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

y = - 2x + 2

Explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute (- 3, 8 ) into the partial equation

8 = - 2(- 3) + c = 6 + c ( subtract 6 from both sides )

2 = c

y = - 2x + 2 ← equation of line
