    well the slope intercept form of the line is y = mx + b m = slope and b = y-intercept you know m = 2 so the equation is y = 2x + b to find b, substitute the point x = 3 and y = -4 hope it helps

    almost y = -4 and x = 3 so its \[-4 = 2 \times 3 + b\] now solve for b

    first find b like this y=2x+b..........eq#1 -4 = 2(3) + b b=-10 now put b=-10 into eq#1 and you will get y= 2x-10
