Please help with math super simple I just don’t know how to do it { on the verge of crying please help }

a)
y = mx + c
m = slope
c = y-intercept
slope = 3
b)
y-intercept = (0, 28.6)
c)
The graph is a line running bottom-left to top-right with a slope of 3. To draw the graph you need to connect two coordinates.
y-intercept = (0, 28.6)
0 = 3x + 28.6
x = - 143/15
x-intercept = (- 143/15, 0)
Draw the axes and label them x and y.
Please don't cry, have an ice-cream.
