Question

What equation represents the line that passes through the points (-3 7 and (3 3?

Answer 1

Hello : let  A(-3,7)    B(3,3)
the slope is :   (YB - YA)/(XB -XA)
(3-7)/(3+3)  = -2/3
an equation is : y=ax+b     a is a slope

y = (-2/3)x +b

 

the line through point B (3,3) :  3 = (-2/3)(3)+b
b =5 
the equation is : y =(-2/3)x+5
