Question 223763: Please help me solve these problems: y=-7x+4 Find the slope, if it exists.
Use the equation below and the indicated value to find an ordered pair that is a solution of ( ,27) y=5x-3.
Decide whether the pair of lines is parallel, perpendicular, or neither.
2x+4y=6 and 4x-2y=9.
Find the intercepts and then use them to graph the equation 3x+y=6.
Thank you.

You can put this solution on YOUR website! a)
y=-7x+4
y=mx+b
slope=m=-7
b)
y=5x-3
5x=y+3
x=(27+3)/5
x=6
(6,27)
c)
first has a slope of -2
second has a slope of 4
d)
3x+y=6
3(0)+y=6
(0,6) y int
3x+0=6
x=2
(2,0) x int
