Question

Complete the equation of the line through (4, -8) and (8.5).

Answer 1

Answer:

the equation of the line will be y= 13/4x-21

Step-by-step explanation:

To get the equation of the line that passes through both those points, first use the formula y2-y1/x2-x1 to find the slope of the line.

You will get that the slope of the line is 13/4

we can then plug our slope and one data point into our formula for the equation of a line, y=ax+b, to solve for the initial value

When we plug them in we will get 5=13/4 (8)+b

when we solve we will get that our b value is -21
