Answer:
Slope is 2
Step-by-step explanation:
use the y2 - y1 / x2 - x1 method
9 - 5 = 4
over
6 - 4 = 2
so the slope is 2
Answer:
The 3rd, 4th, and 6th are correct but I'm not sure if the second would be correct as well.

Answer:
Blue grape in most expensive
Step-by-step explanation:
Given:
Amount of blue grapes = $18
Number of blue grapes = 4 bags
Amount of green grapes = $6.04
Number of green grapes = 2 bags
Find:
Which grape in most expensive
Computation:
Cost of blue grapes = 18 / 4
Cost of blue grapes = $4.5
Cost of green grapes = 6.04 / 2
Cost of green grapes = $3.02
Blue grape in most expensive
Answer:
x=5, y=1
Step-by-step explanation:
Isolate x for 5x-3y=22
5x-3y=22
Add 3y to both sides
5x-3y+3y=22+3y
Simplify
5x=22+3y
Divide both sides by 5
5x/5=22/5+3y/5
Simplify
x=22+3y/5
Substitute x=22+3y/5
10*22+3y/5-4y=46
Simplify 10*22+3y/5-4y
10*22+3y/5=2(3y+22)
=2(3y+22)-4y
Expand 2(3y+22)
=6y+44-4y
Simplify 6y+44-4y
=2y+44
Isolate y for 2y+44=46
2y+44=46
Subtract 44 from both sides:
2y+44-44=46-44
Simplify
2y=2
Divide both sides by 2;
2y/2=2/2
Simplify;
y=1
For x=22+3*1/5 substitute y=1
y=22+3*1/5
22+3*1=25
=25/5
Divide the numbers;25/5=5
=5
x=5
The solutions to the system of equations are;
x=5, y=1
