Analiza Group Title What is the slope of the line 5x - 2y = -10? 2 years ago 2 years ago

1. ash2326 Group Title

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

2. Analiza Group Title

Idk how to.

3. ash2326 Group Title

divide whole equation by -2

4. Analiza Group Title

Even the 5x?

5. JayDS Group Title

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 Group Title

yeah

7. JayDS Group Title

try it yourself and then check with mine.

8. Analiza Group Title

I got x=1?

10. JayDS Group Title

show me ur working out @Analiza?

11. GiggleSquid Group Title

sorry to stike you down jay

12. Analiza Group Title

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

13. JayDS Group Title

can you understand the steps I did?

14. JayDS Group Title

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. JayDS Group Title

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

16. laxkid Group Title

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

17. JayDS Group Title

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.
