well, -12+7 is 5 times (23-7=16) so that answer is 80 and 6-(-5*4=-20) so that is also 16
Slope is equal to the change in y over the change in x,<span> or 'rise over run'.
</span><span>m=change in y/change in x
</span>The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise<span>).
</span><span>m=y^2−y^1/x^2−x^1
</span>Substitute in the values of x and y into the equation to find the slope<span>.
</span><span>m= 1/2 −(− 3/2 )/ 3/5 −( 2/10 )
</span><span>Simplify.
</span><span>m=5
The slope is 5</span>
Y=kx is the direct variation equation
First plug in the x, y values given to find K
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation.
y=3.6x
Plug in the x value to solve for y.
y = 3.6(11)
y= 39.6
