Q:
# 50 POINTS!! HELP!1) What is the equation, in point-slope form, for a line that goes through (8,−4) and has a slope of −5/6 ?y+4=−5/6(x−8)y−4=−5/6(x−8)y+4=−5/6(x+8)y−4=−5/6(x+8)2)What is the equation of a line, in point-slope form, that passes through (−8, 1) and has a slope of 5/6 ?y+1=5/6(x−8)y+8=5/6(x−1)y−8=5/6(x+1)y−1=5/6(x+8)3) What is the equation in point-slope form of the line that passes through the points (7,5) and (−4,−1) ?y−1=6/11(x−4)y+4=11/6(x+1)y+1=6/11(x+4)y+1=6/7(x+4)4) What is the equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) ?y+3=−2(x−5)y+3=−12/7(x−5)y−3=−2(x+5)y−3=−12/7(x+5)5) Plot the line for the equation on the graph.y−4=−1/4(x−5)

Accepted Solution

A:

i dont have time to do all of it (sorry)but this is how you do the point and slope questions:use the equation: y-y1 = m(x - x1)y1 is the y point you are givenx1 is the x point you are givenm is your slopesubstitute all of those in from the questionthe first one is:y --4 = -5/6(x-8)-- turns into a plus so the answer would bey+4 = -5/6(x-8)
