Ato the second -5bc-1 a equals 7 b equals 3 and c equals 2

49-30-1= 18
7 to the second power is 49
3 times 2 is 6; 6 times 5 is 30
and then subtract regularly

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!
