Answer:
Step-by-step explanation:
The easiest way to find the y-intercept would be to put the equation into slope intercept form(y = mx + b). In the equation, b is the y-intercept. So we have to find b.
5y = 20 - 15x
Divide both sides by 5
y= -3x + 4
Now that it is in slope intercept form, we can look at what is plugged in for b, which is 4. So the y-intercept is 4.
