9: 45 it takes 47 minutes what time will i arrive

You will arrive at 10:22.  You would do 47 plus 9:45 and add over extra time to next hour

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!
