Keisha is reading a 350 page book at a rate of 27 pages per day. Use a point-slope equation to determine how many pages she will have left to read after reading the book for 10 days.
How many pages will Keisha have left to read after 10 days?

Lizzy is tiling a kitchen floor for the first time. She had a tough time at first and placed only 9 tiles the first day. She started to go faster and by the end of day 4, she had placed 39 tiles. She worked at a steady rate after the first day. Use an equation in point slope form to determine how many days Lizzy took to place all of the 100 tiles needed to finish the floor. Solve the problem using an equation in point slope form.
How many days did it take Lizzy to place all of the tiles?

At higher altitudes, water boils at lower temperatures. This relationship between altitude and boiling point is linear. At an altitude of 1000 feet, water boils at 210° F. At an altitude of 3000 feet, water boils at 206° F. Use an equation in point slope form to find the boiling point of water at an altitude of 7000 feet. Solve the problem using an equation in point-slope form.
What is the boiling point at 7000 feet?



Enter an equation in point slope form for the line containing the points (-5, 5) and (5, -5).


Enter an equation in point slope form for the line.
Slope is 3 and (-6, -1) is on the line.

Formula: (y-y1/y2-y1 = x-x1/x2-x1)

For the line containing the points (-5,5) and (5,-5)

The Equation is 10x+10y=0

The Equation in point slope form for the line, of slope 3 and (-6,-1)
is 3x-y+17=0

an equation in point sloe form for the line containing the points (5,7) and (6,3) is 3x+2y=27
