Answer:
y = - 3x - 8
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 , then
y = - 3x + c ← is the partial equation
To find c substitute (- 1, - 5) into the partial equation
- 5 = 3 + c ⇒ c = - 5 - 3 = - 8
y = - 3x - 8 ← equation of line
Answer:
y = -3x + -4
Step-by-step explanation:
y = mx + b
to find the y-intercept we need to add or subtract (in this case it's add) a number to x to get to 0.
x = -1.
to get to 0, you need to add one
do that same thing to y
[tex](-1, -5) + (1, 1) = (0, -4)[/tex] therefore the y-intercept (or b) is negative 4.
