Answer:

y = -5x - 3

Explanation:

The slope-intercept form og an equation is y = mx + b, where m is the slope and b is the y-(the value of y when x is zero).

We are given the slope, m, as - 5

y = -5x + b

We need a value of b that will shift the line so that it intersects (-2,7), Find b by entering the point into the equation:

y = -5x + b

7 = -5*-2 + b for (-2,7)

b = -3

The equation is y = -5x - 3

See the attached graph.
