You can solve this by cross multiplying. Set up two ratios of how many pounds of apples over how many pies.
=
Cross-multiply
5x = 2 (20) Multiply
5x = 40 Divide
x = 8
You need
8 pounds of apples to make 20 pies.

Answer:
mx is the slope. b is the y-intercept
Step-by-step explanation:
the first thing you should always do is identify your slope this is key for graphing. remember your slope is b so what ever b is you locate that point in the x axis.
then whatever your slope is remember that it is rise over run so say your equation is y=3x+5 you plot the point on the y intercept which is 5. now 3x is your slope so you put it as a fraction to make it easier this is what it looks like in a fraction "3/1" so you go up 3 on the graph and over 1 because of rise/run
X-4y=6. 5x+y=8
minus X from both sides
4y=6. 4x+y=8
minus y from both sides
3y=6. 4x=8
y=2
X=-2
