Answer:
y=2x-5
Step-by-step explanation:
The slope-intercept form of an equation looks like y=mx+b. Where m is the slope and b is the y-intercept. The slope is already given to us, so m is 2.
To find b use the equation 
. So, to find the y-intercept use b=-7-(2*-1). This equals b=-5.
So, plug in the values to get the final equation y=2x-5.
Answer:
x=-3
Step-by-step explanation:
This is a graph with a super steep slope. So this graph is x=-3. So u are correct!
Answer:
3.28
Step-by-step explanation:
You want to find the discount price. Set a relation to where the well i cant really explain it but do 20/100 = x/16.40 because 100% of the price is 16.40 dollars. You want to find 20% of that so you find what you multiply to 100 to get 16.40 which is 6.0975. Then you do the same thing for the 20% to find 20% of the price which is 3.28. sorry im trash at explaining but i hope i helped.
