shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.
for each child she ears $4 that is the slope m = 4
she paid $10, that is the initial amount paid. so 10 is the y intercept b
m =4 and b = 10
y intercept is 10 so the point is (0,10)
we start graph from y intercept (0,10)
slope = 4 . we know slope = rise / run
slope = 4 or 4/1 are same
rise = 4 and run = 1
for rise we move 4 units up and for run we move 1 unit to the right
the graph is attached below
x axis is the number of child she attends
y axis is the amount she earns
