Question

Hi! could i get some help on this pls! ty

Answer 1

Left Blue Dot (5,9)

Right Blue Dot (7,0)

m = (y2 - y1)/(x2-x1)

= (9-0)/(5-7)

=9/-2

m = -9/2

Don't know the y-intercept so use the formula below to calculate equation of line

y-b = m(x-a)

y-9 = -9/2(x-5)

y-9 = -9x/2 + 45/2

y = = -9x/2 + 45/2 + 18/2

y = -9x/2 + 63/2
