Hi can someone do this and provide the work.

Askateboard ramp is in the shape of a right triangle what is the height of the ramp

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
