sum1 help with my test asap Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8). (Points : 2) y = -2x - 4 y = -2x - 8 y = -2x + 18 y = -2x – 12

    put the information into pint-slope form first

    point-slope is y - y1 = m(x - x1)

    so y-8=-2(x-2)?

    y + 8 = -2(x - 2)

    yes, and now "solve for y" to get it into slope-intercept form

    right now it's in point-slope form. so do the same thing we did to the last one for this one

    for the last one, we distributed, correct? just do the same thing with this one. 1/2 times x is 1/2x and 1/2 times -8 is..?

    ok. let's take this by steps starting with what we started with y - 3 = 1/2(x - 8) y - 3 = 1/2x - 4

    we need to continue to get into slope-intercept

    +3 n +3 so y=1/2+1
