Pleas help me this is 9th grade math help me if you are a nice person I love you

D.) This system has no solutions (The one you chose is correct)

Step-by-step explanation:

y = 8x + 9

-8x + y = -1

-8x + y = -1

y = 8x - 1

These two lines will also never meet as the slope are both 8, but the y-intercept is different, to check, look at the graph below.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )

i don't think there is enough
