Answer:

-10 = b

Step-by-step explanation:

y=mx+b    substitute numbers for the variables

5= -3(-5)+b

5=15+b

-15 -15

-10= b

Answer:

y = - 3x - 10

Step-by-step 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 = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (- 5, 5) into the partial equation

5 = 15 + c ⇒ c = 5 - 15 = - 10

y = - 3x - 10 ← equation of line
