Question 8006: (1,-3) and(3,-5)Write an equation

First, find the slope of the line that connects the two points given.
Then, write the general equation of a line with that slope.
Last, calculate the y-intercept of the line.
Some useful equations for doing this work:
The slope+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
The slope-intercept equation of a line is y+=+mx+%2B+b where m is the slope.
The y-intercept is the value of y when x+=+0.
Try doing the work before looking at my work below:
slope+=+%28-5+-%28-3%29%29%2F%283-1%29=%28-5%2B3%29%2F%283-1%29=-2%2F2=-1
y+=+-x+%2B+b
-1=%28-5-y%29%2F%283-x%29=%28-5-y%29%2F%283-0%29=%28-5-y%29%2F3 putting in the point (0, y)
-1=%28-5-y%29%2F3 to calculate the y-intercept
-3+=+-5-y [multiplying both sides by 3
2+=+-y [adding 5 to both sides]
y+=+-2 [multiplying both sides by -1 and rearranging]
So the equation is
y+=+-x+-+2
