What is the equation for slope intercept form?
y = mx + b
Solve: y = -11 + x and y = 19 - 2x
What is (10, -1)?
What is the pythagorean theorem? What kind of triangles does this work for?
a2 + b2 = c2 Right Triangles

At her job, Ashley is paid $40 for the day. When she drives her car for work she is paid an additional $0.52 per mile. Write an equation to represent how much she earns in a day. How much is Ashley paid for the day if she drives 100 miles in her car?
y = 40 + 0.52x $92
A right triangle has one side length of 5 and a hypotenuse length of 13. Write an equation using the pythagorean theorem that would solve for the third side.
a2 + 52 = 132
OR
52 + b2 = 132
The equation of the linear function that passes through the points (1, 2), (3, 5), and the y intercept (b) is 2.
Hint: y = mx + b --> Need to find the slope.
