Hi guys,I need help on find an equation for these problems,here's how it looks like:
Write an equation for each line.Then graph the line.
38. through (-2,1) and parallel to y=-3x+1
39. through (-3,-1) and perpendicular to y=-2/5x-4
40. through (-7,10) and horizontal
41. through (1,-2/7)and vertical
Now the first two,I know how to do,but the second two are the ones I don't know how to do.Please help me.
Thanks in advance.
