Question

which is the equation of the line that passes through (-10, 8) and (5, 5)?

A) y= -1/5 x + 6
B) y= -3/5x + 7
C) y = 1/5x +3
D) y= -1/5x+5

Answer 1

It's D

Answer 2

First find the gradient/slope m by using the following formula.
\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]
Here
\(x_1=-10\)
\(x_2=5\)
\(y_1=8\)
\(y_2=5\)
Can u find it @kbmathhelp?
