What is the gradient of the graph shown?
Give your answer in its simplest form.

Ahas the coordinates (–4, 3) and b has the coordinates (4, 4). if do,1/2(x, y) is a dilation of △abc, what is true about the image △a'b'c'? check all that apply. ab is parallel to a'b'. do,1/2(x, y) = the distance from a' to the origin is half the distance from a to the origin. the vertices of the image are farther from the origin than those of the pre-image. a'b' is greater than ab.

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.
