Question

Find the equation of the line through the points (-3-3) and (5,4) Give your answer in slope intercept form.

Answer 1

hello :

Hello : let A(-3,-3) B(5,4)
the slope is : (YB - YA)/(XB -XA)
(4+3)/(5+3) =7/8
an equation is : y=ax+b a is a slope

y = (7/8)x +b

the line through point (5,4) : 4 = (7/8)(5)+b
b = - 3/8
the equation is : y =(7/8)x- 3/8
