Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
There can't be a point-slope form until you have TWO points.
A single point doesn't have any other form.
There are an infinite number of lines that all go through a single point.
Every one of them has a different slope, and a different point-slope form.
A )
3 j + 5 p = 7.60
j + 2 p = 2.90
B )
j = 2.90 - 2 p
3 ( 2.90 - 2 p ) + 5 p = 7.60
8.70 - 6 p + 5 p = 7.60
p = $1.10
j = 2.90 - 2.20
j<span> = $0.70</span>
C )
The bill for 1 glass of orange juice and 1 pancake special would be:
0.70 + 1.10 = $1.80
