Need to know the slope and the y intercept

Answer: Slope (M) = 7.5
Y-intercept (B) = 0
Step-by-step explanation:
For the slope, the first step is to find your "pretty points" (spots on the slope that hit the corner perfectly, like (0, 0) or (2, 15).
Now, make a triangle with the two points. Count the amount of squares on both. This will give you 3 and 4, but when taking the units into consideration, 15 and 2. The last step is to divide 15 and 2 which gives you 7.5. I would recommend writing both 15/2 and 7.5 but it's up to you.
The Y-intercept is just the spot where the Y is 0, or where the line touches the Y-axis. This is at the origin, where both X and Y are 0, so your Y-intercept is 0.
I'm kinda bad at explaining things in words, so sorry if this makes no sense, but I hope this helps!
