Answer:
id be happy to help, what grade level so i can prepare?
21/22
use y2-y1 / x2-x1
(9-(-12)) / (3-(-19))
21/22
2x + 12y = -1
12y = -2x - 1
y = - 1/6x - 1/12...slope here is -1/6. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular line will need a slope of 6.
y = mx + b
slope(m) = 6
(0,9)...x = 0 and y = 9
sub and find b, the y int
9 = 6(0) + b
9 = b
so ur perpendicular equation is : y = 6x + 9 <==
36/48 simplified is 3/4
divide both by 12
36÷12
3
48÷12
4
