Which set of coordinates satisfices the equation 3x-2y=15 and 4x-y=20

its an acute right triangle

step-by-step explanation:

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

1/6
