Question

plz help!!
Find the value of r so that the slope between the points is 4. (6, -2) and (r, -6)
a. -5
b. 5
c. -42
d. 4

Answer 1

B 5 as 4=(-6-(-2))/r-6=-4/r66
therefore r-6=-1 r=5

Answer 2

\[m=\frac{ y_2{}-y_{1} }{ x_{2}-x_{1} }\]

where a coordinate is
\[(x_{1},y_{1})\]

since you have 2 coordinates, your other will be \[(x_{2},y_{2})\]

so use these values and substitute to find m, which is the slope

we know m=4
so you have
\[4=\frac{ y_2{}-y_{1} }{ x_{2}-x_{1} }\]

Answer 3

then you would solve it for r
