The Meaning<span> of </span>Slope<span> and </span>y-Intercept. in the Context of Word Problems. In theequation<span> of a straight line (when the </span>equation<span> is written as "</span>y<span> = mx + b"), the </span>slope<span> is the number "m" that is multiplied on the x, and "b" is the </span>y-intercept<span>, where the line crosses the </span>y<span>-axis.</span>

They are simplified. 2 1/6 cannopt be simplified neither can 7 1/3
