write the equation of the line that passes through (7,6) and (-1,2) in slope intercept form. please please help!​
Lana71 [14]

Answer: y = \frac{x}{2} + 2.5

Step-by-step explanation:

The formula for finding the equation is given as :

\frac{y-y_{1} }{x-x_{1} } = \frac{y_{2}-y_{1} }{x_{2}- x_{1} }

From the points given:

x_{1} = 7

x_{2} =-1

y_{1} = 6

y_{2} = 2

Substituting into the formula , we have:

\frac{y-6}{x-7} = \frac{2-6}{-1-7}

\frac{y-6}{x-7} = \frac{-4}{-8}

\frac{y-6}{x-7} = \frac{1}{2}

2(y-6) = x -7

2y - 12 = x -7

2y = x - 7 + 12

2y = x + 5

y = \frac{x}{2} + \frac{5}{2}

y = \frac{x}{2} + 2.5
