    to graph this line start at y_intercept (0,4) use slope to plot points from there slope = -1 (slope is always coefficient of x when in slope-intercept form) slope = rise/run go down 1 then over 1

    dont be :) ok slope is always number next to x slope = 3 y_intercept is always the constant y_intercept = -2 so start at (0,-2) for 1st point then use slope (up 3 over 1 )to get next point

    2/5 (10x + 25) = -10

    ok distribute first 4x +10 = -10 subtract 10 on both sides 4x = -20 divide by 4 on both sides x = -5
