A student evaluated 19.1+(4.32+6.9) and got 69.2 how can you use estimation to convince the student that this answer is not reasonable need answer ASAP please

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.

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!
