CAN SOMEBODY PLEASE HELP ME?!
A line passes through point A(12,18). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.
PLEASE! PUT THIS IN POINT SLOPE FORM!

Answer:

y - 18 = -1.5(x - 12)

Step-by-step explanation:

A = (12, 18)

B=(1.25(12), 0.75(18)) = (15, 13.5)

 

Find slope:  m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5

 

Point slope form:  y - y1 = m(x - x1)

Using point A as (x1, y1)

 

y - 18 = -1.5(x - 12)
