here is part of a railway timetable what time does the first train get to oakengates b) if you catch 0852 from telford central how many minutes should it take to get to shrewsbury

The expression of this would be 3.75x+y= 23

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!
