Question

Find the equation in slope intercept form passing through the points (7.2, 3.8) and (9.1, 9.1

Answer 1

HI, FIRST FIND YOUR SLOPE m=(y2-y1)/(x2-x1)=(9.1-3.8)/(9.1-7.2)=5.3/1.9=2.789
now at point(7.2,3.8) use the formula
y-y1=m(x-x1)
y-3.8=2.789(x-7.2)
y=2.789(x-7.2)+3.8
y=2.789x-20.08+3.8
y=2.789x-23.88 ans....
