Starting with the point-slope formula $y-y_1=m(x-x_1),$ solve this expression for $x$ in terms of $x_1,y,y_1,$ and $m.$

Starting with the standard form of an equation $\text{A}x\text{ + B}y\text{ = C,}$ solve this expression for y in terms of $A,B,C,$ and $x.$ Then put the expression in slope-intercept form.

Use the above derived formula to put the following standard equation in slope intercept form: $7x-5y=25.$

Given that the following coordinates are the vertices of a rectangle, prove that this truly is a rectangle by showing the slopes of the sides that meet are perpendicular.

$(\mathrm{-1},1),(2,0),(3,3)\text{,}$ and $(0,4)$

Find the slopes of the diagonals in the previous exercise. Are they perpendicular?

The slope for a wheelchair ramp for a home has to be $\frac{1}{12}.$ If the vertical distance from the ground to the door bottom is 2.5 ft, find the distance the ramp has to extend from the home in order to comply with the needed slope.

If the profit equation for a small business selling $x$ number of item one and $y$ number of item two is $p=3x+4y,$ find the $y$ value when $p=\text{\$}453\text{ and }x=75.$
