The product of 4 and the sum of a number and 12 is at most 16

    4(x + 12) ≤ 16
4(x) + 4(12) ≤ 16
       4x + 48 ≤ 16
             - 48  - 48
               4x ≤ 32
                4      4
                 x ≤ 8

Solution Set: (8, ∞)

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
