Suppose a line has slope -2/3 and passes through the point (1,8) which other point must also be on the graph A) (7,4)
B) (7,12)
C) (-5,4)
D) (-5,-12)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

d. corresponding side lengths in similar triangles are proportional in length.
