Question

I need help on number 9

Answer 1

y=5/8x-10

Also for 8, the y-intercept means -10 meters in depth.

Answer 2

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
