Write an equation of a line with the given slope and y-intercept. m = - 5, b = - 7 y = - 5x + 7 y = - 7x - 5 y = - 5x - 7 y = 5x - 7

Since b equals the y-intercept, we automatically know that the answer will be in slope-intercept form which is y = mx + b where m equals slope and b equals the y-intercept.

Given.

m = - 5, b = - 7

Slope intercept formula.

y = mx + b

Plug in m = - 5 and b = - 7.

y = - 5x - 7 ← Choice C

y = - 5x - 7

Step-by-step explanation:

The equation of a line in slope - intercept form is

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

here m = - 5 and b = - 7, hence

y = - 5x - 7 ← equation of line
