Answer:
y=1/2x+4 1/2
Step-by-step explanation:
You first find the slope, which is (y1-y2)/(x1-x2)
So in this case, it is 5-1/1-3, which equals -1/-2=1/2
So now that you have m, you plug in y and x using either point, in this case i will use (1,5)
Slope intercept form is y=mx+b
Y is y point, m is slope, x is x point, and b is y intercept
So the equation is 5=1/2(1)+b
you solve the equation and get
5=1/2+b
4 1/2=b
so the final equation in slope intercept form is y=1/2x+4 1/2
