Answer:
D
Step-by-step explanation:
IF you count the dots for each graph, you would see that the minimum for B is Higher than group A's maximum, Therefore, the numbers do not overlap. This means that at a simple glance you can see which company does better.
Y = mx + b, m = slope and b = y-intercept
Because you don't have the y-intercept, you take the equation and replace x and y with the values given, then solve for b and replace b in the original equation with the value found.
y = 2/3x + b
0 = (2/3)(-3) + b
0 = -2 + b
2 = b
y = 2/3x + 2 is the answer
2 · 7.5 + 2 · 11 = 15 + 22 = 37
Wouldn’t that just be 325m=c
Then for the second part it’s just 325(7)=c
Multiply 325 times 7 and that’s the answer
