Answer:
9. y = 1/8x -10
Explanation:
Slope-intercept form is ...
y = mx + b . . . . . . equation of a line with slope m and y-intercept b
The answer to question 7 tells you ...
m = 1/8
The answer to question 8 tells you ...
b = -10
Putting these values into the slope-intercept form gives the equation that answers question 9:
y = 1/8x -10
