Will pick brainiest answer and u have to be my friend what is 5 1/3 + 4 2/5

The answer is 146/15.

Change the mixed numbers from mixed numbers into fractions, so you would have:
16/3 + 22/5
Now to add these two together, they have to have the same denominator. To do that, multiply 16/3*5/5 and 22/5*3/3 and your new terms would be:
80/15 + 66/15
Now you can add the numerators together:
146/15
and simplify for your
9 11/15

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!
