A1.4 m tall child is standing next to a flagpole. the child's shadow is 1.2 m long. at the same time, the shadow of the flagpole is 7.5 m long. how tall is the flagpole?

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!
