Question

Find an equation of the line that goes through the points (7,8) and (4,-8). Write your answer in the form y=mx+b .y= x+ Preview m : ; Preview b : Write your answers as integers or as reduced fractions in the form A/B.Submit QuestionQuestion 2

Answer 1

For this question we will use the two points formula for the equation of a line:

`y-8_{}=(-8-8)/(4-7)(x-7)\text{.}`

Solving for y we get:

`\begin{gathered} y-8=(-16)/(-3)(x-7), \\ y-8=(16)/(3)x-(112)/(3), \\ y=(16)/(3)x-(112)/(3)+8, \\ y=(16)/(3)x-(88)/(3). \end{gathered}`

Answer:

`y=(16)/(3)x-(88)/(3).`
