Slope-Intercept
What is slope-intercept form?
y = mx + b
What is point-slope form?
y - y1 = m (x - x1)
What is standard form?
Ax + By = C
What makes two lines parallel?
They have identical slopes.
y - intercept
What is the slope-intercept form of a line with a slope of 1/3 and a y-intercept of -2?
y = 1/3x - 2
What is the point given in the following equation:
y - 3 = 1/2(x + 4)
(-4, 3)
The Ramy family bought 4 sandwiches and 3 salads. They spent $24.
Which equation below shows the Ramy Family situation in Standard Form?
Let x = sandwiches and y = salads
4x + 3y = 24

What is the equation of the line in point-slope form that passes through the point (-2, 1) with a slope of 3?
y - 1 = 3(x + 2)
You are in charge of buying food for your family reunion. You spend $90 on hamburgers and turkey burgers. You pay $1.25 for each hamburger and $2.00 for each turkey burger. Let x be the number of hamburgers and y be the number of turkey burgers?
What is the equation in standard form that represents your situation?
1.25x + 2y = 90
Label the following equations as Parallel, Perpendicular, or Neither.
y = 1/3x - 4 and y = -3x + 19
Perpendicular
What is the slope formula?
m = y2 - y1 / x2 - x1
Find the line in slope-intercept form that passes through the coordinates (2, 6) and (-2, 4)
y = 1/2x + 5
Draw the graph of y - 5 = 3(x + 1)

What is 3x - 4y = 12 in Slope-Intercept form?
y = 3/4x - 3
Label the following equations as Parallel, Perpendicular, or Neither.
y = 2/3x - 7 and y = 3/2x - 7
Neither
What is Ms. Kelly's favorite color?
Blue.
Find the line in slope-intercept form that passes through the coordinates (2,5) and (2, 12).
It's a vertical line (up and down) so the slope is undefined.
x = 2
What are the equations of the line in point-slope form that passes through the points (4, 2) and (1, 6)?
y - 6 = -4/3(x - 1)
y - 2 = -4/3(x - 4)
What is 6x + 2y = 18 in slope intercept form?
y = -1/3x + 3
