Question

Write the equation of the line that passes through the points (-2,-1)(−2,−1) and (2,4)(2,4). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Answer 1

Answer: y= 5/4 + 3/2

Step-by-step explanation: Your equation is y=mx +b. You have to subtract the second y from the first y, and the second x from the first x to find the slope. This equation would be 4-(-1) over 2-(-2). So your slope will be 5/4. Now to find the y-intercept you can choose either (x,y) point. For example if you are using (2,4) you would do b= 4-(5/4)(2). b=3/2.
