For (8, 16): 3(8) - 8 = 24 - 8 = 16 [solution]
For (3, 4): 3(3) - 8 = 9 - 8 = 1 [not a solution]
For (-6, -26): 3(-6) - 8 = -18 - 8 = -26 [solution]
For (-10, -38): 3(-10) - 8 = -30 - 8 = -38 [solution]
Answer:
y = -8x + 4
Step-by-step explanation:
Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.
In this case, the slope is -8 and the y-int is 4 so we naturally plug those in
Y = -2x + 5 y =3x - 2
Since both equations are equal to 'y' you can set them equal to each other to solve.
-2x + 5 = 3x - 2 Subtract 3x from both sides
-5x + 5 = -2 Subtract 5 from both sides
-5x = -7 Divide -5 on both sides
x = 7/5
Plug 7/5 back in for x and solve for y.
y = -2(7/5) + 5
y = (-14/5) + (25/5)
y = 11/5
(7/5, 11/5) OR (1.4, 2.2)
The x intercept represents the maximum number of books he can buy
