Did she solve the problem correctly? Yes. She solved the problem correctly. No. She multiplied the dividend by the divisor instead of finding the reciprocal. No. She multiplied the denominators instead of finding a common denominator. No. She multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor

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!
