Answer:
y = -1
Step-by-step explanation:
Using slope intercept form:
y = mx + b
slope (m) = 0
x = -3
y = -1
The only variable that is unknown is the y-intercept, b. You can find this by plugging the values above into slope intercept form:
-1 = (0)(-3) + b
-1 = 0 + b
b = -1
Since the slope is zero, the "mx" part of equation can be taken out since 0 times x will always be 0. When "mx" is taken out of the equation, b remains.
So the equation of the line is:
y = -1
