Please help and do this in Point Slope Intercept, show your work.

(-4,4) (5,-14)

slope: -2   y intercept: -4   x intercept: -2

Step-by-step explanation:

slope (m) = (-14 -4) / (5 - -4) = -18 / 9 = -2

y intercept (b) = y - mx = 4 - (-2)x(-4) = 4 - 8 = -4

equation: y = -2 x - 4

x intercept:  y = 0 x = -2

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
