To find the X intercept, make Y equal to 0. To find the Y intercept, make X equal to 0.
5x - 2(0) = 20
5x = 20
x = 4
5(0) - 2y = 20
-2y = 20
y = -10
Answer:
1. 12
2.
a can be a triangle (obtuse)
b can be a triangle (acute)
Step-by-step explanation:
Answer:
y = 8x + 70
Step-by-step explanation:
Start with the third line.
x = 3, y = 94
Subtract 1 from x and 8 from y:
x = 2, y = 86; this is the second line
Subtract 1 from x and 8 from y:
x = 1, y = 78; this is the first line
Subtract 1 from x and 8 from y:
x = 0; y = 70
For selling 0 games, she earns $70.
y = mx + b
y = mx + 70
For each game she sells, her commission is $8.
y = 8x + 70
