Answer: $1.75
Step-by-step explanation:
Assume hamburgers are x and French fries are y.
Use a simultaneous equation to solve;
2x + y = 4.75
3x + 3y = 9.00
Using substitution;
2x + y = 4.75
y = 4.75 - 2x
Solving it;
3x + 3y = 9
3x + 3 * (4.75 - 2x) = 9
3x + 14.25 - 6x = 9
-3x = 9 - 14.25
-3x = -5.25
x= -5.25/-3
x = 1.75
y = 4.75 - 2x
= 4.75 - 2 * 1.75
= 1.25
Hamburgers are x so they cost $1.75 each.
Slope is -1

Answer:
Step-by-step explanation:
To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points. Label the legs of the triangle.

Answer:
Step-by-step explanation:
for this graph find rise over run , and where the line crosses they y axis.. sooo ..
it crosses at -2 and the slope is rise over run or y/x and I can see by the graph that the line goes up 1 when it goes over 1... so the slope is +1
sooo...
use the slope intercept form y = mx + b
y = 1x + (-2)
y = x - 2 :)
