## anonymous 4 years ago What is the slope of the line 5x - 2y = -10?

1. ash2326

Could you rearrange the equation such that, it's of the form $y=mx+c$ ?

2. anonymous

Idk how to.

3. ash2326

divide whole equation by -2

4. anonymous

Even the 5x?

5. anonymous

rearrange it into the form of y = mx + c so 5x - 2y = -10 5x + 20 = 2y 2y = 5x + 20 y = 5/2x +20/2 y = 5/2x + 10 now the m = gradient or slope that you can read from the last line of the rearranged equation so what is it?

6. ash2326

yeah

7. anonymous

try it yourself and then check with mine.

8. anonymous

I got x=1?

show me ur working out @Analiza?

11. anonymous

sorry to stike you down jay

12. anonymous

I got confused, how m I supose to divide -2y & 5x?

13. anonymous

can you understand the steps I did?

14. anonymous

5x - 2y = 10 so we want y to be on one side so we will have to +2y on both sides 5x -2y + 2y = 10 + 2y 5x = 10 + 2y now we have to minus 10 on both sides 5x - 10 = 10 -10 + 2y 5x - 10 = 2y now we are going to rewrite it 2y = 5x - 10 this is same as the previous step but just swapping them around y = 5/2 - 10/2 divide both sides by 2 y = 5/2x - 5

15. anonymous

lets try an easier sample, say 2x + y = 1, and rearrange into the form on y= mx + c

16. anonymous

slope is $\frac{5}{2}$

17. anonymous

yes, @laxkid we figured that out already

I can see that you have trouble rearranging basic equations, so I think you should start by doing some exercises.
