D= number of dimes
q= number of quarters
(Keep in mind, it's not the price, but the number of each)
0.1d+0.25q=74.35
d=q+5
0.1(q+5)+0.25q=74.35
0.35q+0.5=74.35
0.35q=73.85
q=211
d=216

Answer:
y=2x-8
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept value.
It says the slope is 2, so we know that y = 2x+b. To find b, plug in a point given. We are given (9,10), so plug that into the equation, where y = 10 and x = 9. 10=2(9)+b, solve for b.
b equals -8, so the answer is y=2x-8.
