Question

What is the slope of the line 5x - 2y = -10?

Answer 1

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

Answer 2

Idk how to.

Answer 3

divide whole equation by -2

Answer 4

Even the 5x?

Answer 5

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?

Answer 6

yeah

Answer 7

try it yourself and then check with mine.

Answer 8

I got x=1?

Answer 10

show me ur working out @Analiza?

Answer 11

sorry to stike you down jay

Answer 12

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

Answer 13

can you understand the steps I did?

Answer 14

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

Answer 15

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

Answer 16

slope is \[\frac{5}{2}\]

Answer 17

yes, @laxkid we figured that out already

Answer 18

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