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

Respuesta :

Answer:

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

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
