slope
m=(-7-2)/(7/3--4/3)
m=-9/(11/3)
m=-9*3/11
m=-27/11
m=-2 5/11

the slope m of the line through (-4%2F3,2) and (7%2F3,-7) is:

m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29

m=%28-7-2%29%2F%287%2F3-%28-4%2F3%29%29

m=-9%2F%287%2F3%2B4%2F3%29

m=-9%2F%2811%2F3%29
m=-9%2A3%2F11

m=-2.4545454545454545454545454545455

m=-2.46
we can also find the equation of the line that goes through point (-4%2F3,2) and has a slope of m=-2.46

y=mx%2B%28y%5B1%5D-mx%5B1%5D%29

y=-2.46x%2B%282-%28-2.46%29%28-1.33%29%29

y=-2.46x%2B%282-3.27%29
y=-2.45x-1.27
