Answer:
y=10x+15
Step-by-step explanation:
The slope intercept form is represent by this equation
Where m is the slope, and b is the y intercept( when x is zero).
Looking at the graph, we already found the y intercept.
When x=0, y is at 15 so our y intercept is 15 so our equation updated look like
Now let find the slope
Slope is
Let use two arbitrary points to find the slope
Let use (3,45) and 6,75).
So our slope is 10 so our equation look like
