Question

HELP PLEASE!
y = -3/2x + 4

Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences.
(the / in -3/2 is a fraction bar)

Answer 1

Ok.... my webpage crashed. Let me type that ALL back out again.... :/

Answer 2

ok thanks

Answer 3

\(\large{y=-\frac{3}{2}x+4}\)

4 is your y intercept, so you would plot a point at (0,4)

Your slope is \(-\dfrac{3}{2}\rightarrow \dfrac{rise}{run}\)

That means that we would go down three from our original point, and right two. (2,1)

Then you draw a line through the two plotted points.

Answer 4

you are amazing!!

Answer 5

No problemo :)

Answer 6

;)

Answer 7

one more question please?

Answer 8

–3x + 2y = 8

Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences.

Answer 9

This one you need to solve for y.

Answer 10

\(\large{-3x+2y=8}\)

\(\large{2y=3x+8}\)

\(\large{y=\frac{3}{2}x+8}\)

Can you do it from there given what I just told you?

Answer 11

well the y is already isloated

Answer 12

Correct, I was referring to this in comparison to the previous problem. The only difference is the slope. Instead of going down three, we go up three.

Answer 13

how do i write this in a complete sentence?

Answer 14

Plot[4 - (3 x)/2, {x, -5.3, 5.3}]

Answer 15

It is literally exactly the same as the first problem..... just instead of going down three, we go up three.

Answer 16

so that means that we would go up three from our original point and right two.

Answer 17

but i still dont understand how i would write this in a complete sentence with the plots. but what are the plots?
