How do you graph an equation using x and y intercepts.

Mathematics
1 answer:
Citrus2011 [14]3 years ago
5 0

Answer:

I'm going to use the following as an example.

2x + 4y = 8

To find the y-intercept, set x equal to 0 then solve for y.

2(0) + 4y = 8

two times zero is zero, so we have the following equation.

4y = 8

Solve for y

\frac{4y}{4}  =  \frac{8}{4}  \\ y = 2

Your first point you will graph is (0, 2).

Now solve for the x intercept. To do this, set y = 0.

2x + 4(0) = 8

4(0) = 0, so you can remove it, and solve for x.

2x = 8

\frac{2x}{2}  =  \frac{8}{2}  \\ x = 4

Now the next point you have is (4, 0). plot that point. Connect the two points with a line and you are done.

poizon [28]

Answer:

The quantity of ground meat he use for hamburgers is                                   2 \frac{13}{80} pounds

Step-by-step explanation:

Given as :

The total quantity of ground meat bought to make hamburgers = 2 \frac{9}{16}

Or, The total quantity of ground meat bought to make hamburgers = \frac{41}{16} pound

The quantity of ground meat left after use = \frac{2}{5} pound

Now, let The quantity of ground meat used for hamburgers = x pound

So, x = The total quantity of ground meat bought - The quantity of ground meat left

Or, x = \frac{41}{16} pound -  \frac{2}{5} pound

Or, x =  \frac{205-32}{80} pound

I.e x = \frac{173}{80}

∴  x = 2 \frac{13}{80} pounds

Hence The quantity of ground meat he use for hamburgers is                        2 \frac{13}{80} pounds  . Answer
