1. 5y+x=15 and y=5x-4 Y=-5x+3
y=5x-4
parallel
perpendicular
neither
exactly one solution
no solution

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

tangent

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
