I need real answers please help i'm having a lot of trouble with this. it been 2 days i can't get

so first take two sets of coordinates. Find the slope using the slope formula; m=(Y₂-Y₁)/(X₂-X₁). Plug in the x and y values. let's use (14,21) and (2,3). Our equation would be (3-21)/(2-14)=(-18)/(-12)=1.5. Then use point-slope form; (Y-Y₁)=m(X-X₁). Plug in the x and y values, and get (y-21)=1.5(x-14). Simplify and get y-21=1.5x-21. Add 21 on both sides, and you get your final equation y=1.5x. So equation 1 will match A. Then do those same steps for the rest of the equations.
