9. Which of the following relations are functions? Choose all that apply. Assume that each different variable (2 points) has a different value.
0{(2,6).(8.a),(6.0). (,d))
{(c, e),(c, d).(0,5)}
O{(6,6).(c, d),(d, C),(0,a)}
{(a, b).(6,c).(0,2).(d, e)}

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!
