The figure shows a line graph and two shaded triangles that are similar: which statement about the slope of the line is true? it is fraction 1 over 2 throughout the line. it is 2 throughout the line. the slope from point o to point a is fraction 1 over 2 time the slope of the line from point a to point b. the slope from point o to point a is two times the slope of the line from point a to point b.
