Question #8dba9

Answer 1

Because this the simple form of y=mx-b
We don't need to work hard
And m=8

[thanks to those who commented]

Explanation:

This is a longer way(you can use it when there isn't the simple version)
First you need two points on the grid
Let's do x=0 and x=1
`y=8xx0-5/2`
`y=-2.5`

And
`y=8xx1-5/2`
`y=5.5`

Now use dose two points `(0,-2.5)(1,5.5)`to find the slope (m)
`m=(y2-y1)/(x2-x1)`
`m=(5.5-(-2.5))/(1-0)`
`m=8`

Answer 2

`"slope "=8`

Explanation:

`"the equation of a line in "color(blue)"slope-intercept form"` is.

`color(red)(bar(ul(|color(white)(2/2)color(black)(y=mx+b)color(white)(2/2)|)))`

`"where m is the slope and b the y-intercept"`

`y=8x-5/2" is in this form"`

`"with slope "=m=8`
