Dados los punto P(−8, −12) Q(4, −4a) y a la recta l : 9y = −6x + 3.
Determine:
a) La ecuación de recta que pasa por los puntos P y Q. (lP Q).
b) Determine (si es posible) el valor de a para que la recta l sea perpendicular
a la recta lP Q
c) Considerando el resultado obtenido en b. determine el punto de intersección
entre la recta l y la lP Q

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

step-by-step explanation:

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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
