Answer 2

i will fan and medal

Answer 3

Pretty please, post just one problem at a time.

Take a look at the first problem. It features 3 inqualities. You'll need to set up coordinate axes and then graph each inequality on the same set of axes.

Answer 4

First inequality: \[x-4y \le8\]

Answer 5

Hint: replace the inequality sign with =. Graph x-4y=8.
suggestion: first let x=0. then -4y=8 and y=-2. Thus, one point on the graph is (0,-2) This is your y-intercept. Find the x-intercept now, please.

Answer 6

ok

Answer 7

will it be (0,3)

Answer 8

First, you let x =0 and found the value of y, which resulted in the point on the line (0,-2).

Now, start over, to find the x-intercept of x-4y=8. Since the x-axis is the line y=0, set y=0 and solve for x. (It's not 3, sorry)

The y-intercept is (0,-2).
The x-intercept is ( ?? , 0). Fill in the blank.

Answer 9

Now graph those 2 points and draw a straight line thru them. Please use the Draw utility, so that I can see your work. Thanks.
