not very good

jim_thompson5910 · Answer

$$\large y=-\frac{3}{4}x+5$$


$$\large y=-\frac{3}{4}(-1)+5$$


$$\large y=\frac{3}{4}+5$$


$$\large y=\frac{3}{4}+\frac{20}{4}$$


$$\large y=\frac{23}{4}$$

So when x = -1, y = 23/4

-----------------------------------------------

$$\large y=-\frac{3}{4}x+5$$


$$\large y=-\frac{3}{4}(-2)+5$$


$$\large y=\frac{6}{4}+5$$


$$\large y=\frac{6}{4}+\frac{20}{4}$$


$$\large y=\frac{26}{4}$$

So when x = -2, y = 26/4

anonymous · Answer

so do I divide 26/4 to brake down to where i could plot the points?

jim_thompson5910 · Answer

you can, so 26/4 = 6  1/2 = 6.5

anonymous · Answer

and 23/4 = 5.75?

jim_thompson5910 · Answer

good, you got it

anonymous · Answer

okay i got it a different way.....I turned 3/4 into -.75

anonymous · Answer

is this okay?

jim_thompson5910 · Answer

3/4 = 0.75 not -0.75

anonymous · Answer

but the it's (-3/4) in the equation...so i turned it into -0.75

jim_thompson5910 · Answer

oh ok, forgot about the negative as all I saw was 3/4


So yes, -3/4 = -0.75
