    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

    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
