Slope
Find the slope between
(2, 10) and (4, 40)
15
Identify the slope and y-intercept of the equation below:
y=-4x +8
Slope (m) = -4
Y-intercept (b) = 8
Solve the system using elimination:
-5x + 4y = 10
5x - 4y = 8
No Solution
What is the slope between
(-4, -10) and (8, -20)
-5/6
Put the following equation into slope-intercept form:
-3x + 2y = -12
y = 3/2x - 6
Solve using substitution:
y = -4x + 2
3x + 2y = -1
(1, -2)
At 3 pm, the temperature outside is 58 degrees and is dropping 5 degrees per hour. What is the slope of the given situation?
-5 or -5 degrees per hour
Write the equation of the given situation in slope-intercept form. Your bank account has $15 in it currently and is increasing $10 per day.
y = 10x + 15 or y = 15 + 10x
Solve using elimination:
2x + 5y = 2
3x - 5y = 53
(11, -4)
What is the slope of a horizontal line?
What is the slope of a vertical line?
Label each.
Horizontal = 0
Vertical = undefined
Write an equation of the line that has a slope of 3/4 and passes through the point (4, 7).
y = 3/4x + 4
Solve the system using elimination:
6x - 3y = 15
7x + 4y = 10
(2, -1)
After the 3 hours of a storm, there were 2 inches of snow on the ground. After 7 hours of the storm, there were 10 inches of snow on the ground. What was the rate at which the snow was falling? Be sure to include a label.
2 inches per hour
Write an equation of the line that passes through the given points.
(2, -5) and (8, -2).
y = 1/2x - 6
You bought 5 Monsters and 4 bags of chips at Casey's for $22.50. Another day you bought 3 Monsters and 2 bags of chips for $12.50. How much do a Monster and a bag of chips costs?
Monster = $2.50
Chips = $2.50
