R: {3, -3}
A $40 shirt is on sale for 30% off. What is the price of the shirt?
What is $28?
Find 30% of 40 and then subtract it from $40.
Evaluate: 3 * 8 + 9 / 3 - 5
What is 22?
Solve: 4x + 3 = 2(3x - 1) + 7
What is x = 1?
Write an equation of a line in slope-intercept form through the point (-1, 3) with a slope of -2.
What is y = -2x + 1?
**You had to write in point-slope first. Then rearrange.
