Can some one please help me?

Height:shadow
so 3.5:1.06 and is the same as 50.5:x
we treat it as a fraction and get
3.5/1.06 and x/50.5

they should be equal
we know that if we multiply two equal fractions, with one flipped, then we will get 1 exg 1/2=4/8    1/2 times 8/4=8/8=1

so 3.5/1.06=x/50.5    3.5/1.06 times 50.5/x=1
176.75/1.06x=1
multiply both sides by 1.06x
176.75=1.06x
divide both sides by 1.06
166.745=x
round up to hundreds place
166.75m=accutal height

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!
