Answer:
y = 6x +24
Step-by-step explanation:
b) Fill in the x- and y-values and do the arithmetic.
m = (72 -66)/(8 -7) = 6/1 = 6
The slope is 6.
__
c) The y-intercept can be found from the slope and one of the points:
b = y -mx
b = 66 -6(7) = 24
The line crosses the y-axis at y=24.
__
d) The slope-intercept equation is ...
y = mx +b
y = 6x +24
