Find the length of the third side. If necessary, round to the nearest tenth.
16
20

12

Step-by-step explanation:

Find the diagram attched

Using the pythagoras theorem;

x² = 20² - 16²

x is the unknown side

x² = 400-256

x² = 144

x = √144

x = 12

Hence the length of the missing side is 12

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!
