A. m∠r = m∠s b. m∠r + m∠s = 180° c. m∠r + m∠s = m∠p + m∠ this is to that to.

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!

I'm not sure but i think it's 1670km/h
