Answer:
Im going to guess that this is a true or false question so..
True :)
Answer:
$42 - 19 = 23 - 15 = $8
Step-by-step explanation:
Well i don't know if this will help but slope intercept form
y=mx+b
M-slope
B-Y intercept
and
(x,y)- would be any point on the graph and if you were to plug those points in for x and y the equation would solve if done properly
Answer:

Step-by-step explanation:
![\text{The slope-intercept formula:}\\\\y=mx+b\\\\m\ -\ slope\\b\ -\ y-intercept\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{From the table we hve two points (0, -1) and (2, 2).
