$3x+4y=25\\
3x-3y=-3|\cdot(-1)\\\\
3x+4y=25\\
\underline{-3x+3y=3}\\
7y=28\\
y=4\\\\
3x-3\cdot4=-3\\
3x-12=-3\\
3x=9\\
x=3\\\\
\boxed{(x,y)=(3,4)}

What is the slope of the line threw (-7,-2) and (-6,7)

miv72 [106K]

Answer:

Step-by-step explanation:

To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Here the points are (-7,-2) and (-6,7). Substitute and simplify.

$m=\frac{7--2}{-6--7}=\frac{7+2}{-6+7}=\frac{9}{1}=9$
