Slope intercept form:
y=mx+b
Where:
m= slope ( y variation/ x variation)
b= y-intercept (where the line crosses the y-axis)
By looking at the graph we can see that the line crosses the y-axis at -2.
b=-2
slope = rise/ run= 3/1 = 3
Equation:
y= 3x-2
Answer:
C
Step-by-step explanation:
The answer is .64
$7.50
$207 / 18 = $11.50
Each bracelet costs $11.50.
$11.50 - $4 = $7.50
She receives $7.50 for every bracelet she sells.
the first one is no it's nonproportional
and the second one it yes its proportional
