Answer:

Explanation:

Answer for 8

5. because y = 4x+5 we can see that if x=0 then y = 4*0 +5 = 5, but if we look at the graph when x=0, y is not 5 (we have actually the point (0, 4) so the graph and the equation do not match)

6. Again, look at the the constant term ( the terms that have no x) is 20 in the equation so on the graph should be the point (x=0, y=20) yet on the graph when x=0 the y = 40 so the graph and the equation do not match.

7. in the equation (x=0, y=50)

in the graph (x=0, y= 50)

so far looks good yet,

in the graph for x=3 , y = 75

in the equation if the x= 3 then y = 25*3 +50 = 75+50 = 125

for the equation and graphs to match they need all points to match

(0, 50) and (0, 50) is good yet ( 0, 75) and ( 0, 125) is not the same
