Answer this question please and thank you and please don’t sound to smart I’m in 6 to grade

Which expression can be used to determine the slope of the line that passes through the points -6, three and one, -9

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
