a lamppost is 6 feet high and casts an 8 foot shadow. At the same time of day, a flagpole near the lamppost casts a 20 foot shadow. using the properties of simalar triangles find the height, h, of 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!
