your slope is 2.5, your first point is at (0,-10) because -10 (b) is your y-intercept
here is the equation format.
y=mx+b
y=2.5x-10
the slope also goes up because it is positive. so you're left with -
A, the vertical intercept is -10
in the future, please put
a)
b)
c)
d)
because I got very confused, thank you
