what is the slope-intercept form of the linear equation whose graph passes through (-2,4) and is parallel to the graph 3x+y=6?

a) y =-3x - 2
b) y =-3x + 10
c) y = 3x - 2
d) y = 3x + 10

which linear equation represents a line that passes through (3,-7) and has a slope of -4?

a) y = -4x-19
b) y = -4x-5
c) y = -4x+5
d) y = -4x+19

  1. what is the slope of the line
    y = -3 x + 6
    ?

    using that slope:
    (y - 4) / (x + 2)= slope
    solve for y
    =================================
    y = -4 x + b
    -7 = -4(3) + b
    b = 5
    so
    y = -4 x + 5

    You absolutely have to be able to do these - practice !!!!!!
