Answer:
y = -5x - 4
Step-by-step explanation:
Slope-intercept form of an equation is y=mx+b. The m is the slope. The given slope is -5 and a point is (-1,1) which is an x (the -1) and a y (the 1) so we can fill these into the equation to find the b value.
In the final answer we'll write y= and then fill in the -5 for the m , write the x and fill in the number that we find for b.
y = mx + b
1 = (-5)(-1) + b
1 = 5 + b Subtract 5
1-5 = 5-5 +b
-4 = b
Now that we know b we can fill it in the equation.
y = -5x - 4
