Answer:
m = -3
b = 8
Explanation:
y = -3x + 8 is in slope-intercept form, which is:
y = mx + b
so the slope is the m, the number right there beside the x. In your equation its -3. The b is the y-intercept, so its the last number tacked on the end of the equation there on the right. For your question, its the 8.
Slope is -3 and y-intercept is 8.
