Answer:
Step-by-step explanation:
<u>Slope intercept form:</u>
- y = mx + b, where m - slope, b - y-intercept
<u>Take two points from the graph:</u>
<u>Find the slope:</u>
- m = (3 - 1)/(3 - 1) = 2/1 = 2
<u>Find the y-intercept using point (2, 1) and the equation above:</u>
- 1 = 2*2 + b
- b = 1 - 4
- b = -3
<u>The line is:</u>

Answer:
y = 9x
Step-by-step explanation:
You can set up linear equations like this: y = mx + b, where m is the slope or rate, and b is the y-intercept.
9 would be the slope, since he has to pay $9 per gift.
The y-intercept is when x = 0, but if he doesn't buy any gifts, he won't have to pay anything, so b = 0. You don't have to include it since it's 0.
So, it's just y = 9x
Hope that helps! :D
I would multiply 46x1x1,000 to get 46,000. the. i would multiply 1x2.2x1 to get 2.2. i would then divide 46,000/2.2 to get 20,909.0909
