There are 7 yellow roses, & pink
roses, 2 black roses and is red roses
in a vase.
what is the probability you would
randomly pick a black rose?
in percentage .

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!
