Question

find the slope:
A. (-2,6), (-4, -7)
B. y = (1/4)x + 2
C. (-4,-4), (-7, 24) HELP!!!!!!!!!!

Answer 1

To find the slope using just cordinates you use this: \[\frac{ y ^{1}-y ^{2} }{ x ^{1}-x ^{2} }\]

Answer 2

So, to do A and C you would start out with your coordinates (I will use A) and input them in the equation. If you do that then your equation should be this:
\[\frac{ 6-(-7) }{ -2-(-4) }\]

Answer 3

Subtracting a negative = adding a positive, so it would be:
\[\frac{ 6+7 }{ -2+4 }\]

Answer 4

Once you solve that, then that is your slope. I hope you'd know how to solve that. Just add the 6 and 7, and the -2 and 4. Then divide it. so 13 divided by 2, which is 6.5. That's your slope.

Answer 5

For one like B, it's already in equation form, slope intercept form. Your slope is:
y=mx+b.
x= x intercept
b= y intercept
m= slope.
Using that information what do you think the slope is?
