Answer:
Slope is 20
y-intercept is 50
Explanation:
y=mx+b is slope-intercept form where m is the slope and b is the y-intercept where x and y are the variables.
For your equation the slope is 20 and the y-intercept is 50 where m and y are variables.
The y-intercept is what you initially start with and here that is 50. The slope is a rate. So you are getting 20 dollars added per month.
