Find the slope of the line passing through the points (–1, 3) and (4, –7). 2 3/4 -4/3 -2
there are a lot of questions like this on the OS look at them

Sara I wish I could Help But I can't Sorry D:
Each point is written (x,y). The formula for the slope of a line is \[\frac{y _{2}-y _{1}}{x _{2}-x _{1}}\] The little two means it's the y or x-coordinate for the 2nd point you pick.
Please tell me if you still don't understand
Could u explain it a little more
Take the x and y coordinates (first and second number in the parentheses) and plug them into the formula I gave you.
First point is (-1,3), second point is (4,-7). \[\Large\text{slope}=\frac{\text{change in y}}{\text{change in x}}\]
ok what next
What is the \(\Large\text{change in y}\)?
3?
No, that is the \(\Large\text{original y}\)
I dont understand
Okay, when we go from the point (-1,3) to (4,-7)
The y-value changed from 3 to -7, right?
yea
Does it make sense to you that \(\Large\text{change in y = new y - original y}\)?
Let's plug those numbers in
ok thanks
