Answer:
y = -(3/4)x + 19
Step-by-step explanation:
If you look at the line, you have the y intercept already. so there is less work to do.
The equation for a linear line is y=mx+b (or c depending on which country you are from) where m is the gradient and b is the y intercept
b = 19 from the diagram
To find the gradient, it is y2-y1/x2-x1, so pick any 2 points, let say (16,7) and (0,19)
m = 19-7/0-16
= 12/-16
=3/-4
Sub the required numbers back into the equation
y = -(3/4)x + 19
