Slope intercept form - <u>y = m(x) + b</u>. m represents slope, b represents the y-intercept. You should be able to plug in any value for y and x into the equation, and it should result in a true statement.

The y-intercept is easy to find. It is the point where X is equal to zero and the graph line crosses through the y axis. In this case, y intersects at -2. Since we insert the y intercept at b, we can go ahead and plug it in there.

y = m(x) + b > <em>y = m(x) - 2 </em>

Since there is only one option with the y intercept equalling -2, you can go ahead and pick D) y = -x - 2 as your answer, since no other options have the correct y-intercept.

Two cylinders are similar. The radius of cylinder a is 5.6 in. The radius of cylinder b is 1.4 in. If the hwight of cylinder b i

sleet_krkn [62]

The answer is 16in.

Let the radius and height of cylinder A be Ra and Hb respectively and the radius and height of cylinder B be Rb and Hb respectively.

Using similar shapes:
Ra/Ha= Rb/Hb
5.6/Ha=1.4/4
Ha=(4×5.6)/1.4
Ha=22.4/1.4
Ha=16in
