Question

If the equation y = -10 + 2.5x was plotted:
Answer

the vertical intercept would be -10.

the slope would be -7.5.

it would graph as a downsloping line.

the slope would be -10.

Answer 1

[y =-10+2.5x
then the slope will be 2.5
and the y intercept is -10
x intercept is 4
since the slope is positive so it has alwyas positive slope

Answer 2

Equation is of the form y = mx + b where m is the slope and b is the y (vertical) intercept.
m = 2.5 slope
b = -10 y (vertical) intercept
dividing both sides by 2.5 yields
y/2.5 = -4 + x
when y=0 x=4 (x intercept)
