Choose the correct slope of the line that passes through the points (-4, 8) and (-3, -6).
Slope is change in y over change in x. Know how to find that?
No please help :)
I dont want answer I wanna know how to do it my self
If the slop is m, then the formula is: \(m=\dfrac{y_2-y_1}{x_2-x_1}\) So you pick one point as \((x_1,y_1)\) and the other as \((x_2,y_2)\) and then you can put them in that formula.
The change in y is the difference in y. Change and difference have similar meanings. Well, difference has a special meaning in math: subtraction. So by subtracting the y of the first point from the y of the second, you get the top value of the fraction. Similarly you find the x for the bottom.
Here is another way to think about it: Some random points, not yours: |dw:1411669925815:dw|
So (-4,8) and (-3,-6)?
|dw:1411669974657:dw|
