Question

Find the equation of a line with the two points
(-10,6) and (-8,7)
Is it A)y+6=1/2(x+10) B)y+10=1/2(x-6) C)y-6=1/2(x+10) or D)y-6=1/2(x-10)

Answer 1

Use the formula
\[
\frac { y-y_1}{x-x_1}= \frac { y_2-y_1}{x_2-x_1}=m\\
y-y_1 =m(x-x_1)

\]

Answer 2

\[
m=\frac { 7-6}{-8+10}=\frac 1 2

\]

Answer 3

(-10,6) and (-8,7)
\[
y-6= \frac 1 2(x+10) \\

\]

Answer 4

Thank you :)
