Find the Slope
(5, 7) and (3, 6)
1/2
A slope of 2.
2 units up, one unit over.
Write an equation in slope-intercept form when slope = 3 and the y-intercept is 2
y = 3x + 2
What is the slope and y-intercept?
2x + 4y = 12
slope = -1/2
y-intercept = 3
A gym membership costs 22$ a month. Write an equation to represent the cost per month using C for cost and m for number of months.
c = 22m
(2, 5) and (8, 1)
-2/3
A slope of -5.
5 unit down, one unit over.
Write in slope-intercept form: slope = 1/4; y-intercept = -6
y = 1/4 x - 6
What is the slope and y-intercept?
-5x + 3y = 15
slope = 5/3
y-intercept = 5
You mow lawns as a job. You charge 15$ per lawn, plus a flat rate of 20$ just to show up. Write an equation to represent how much you charge, using L for number of lawns mowed and M for money made.
M = 15L + 22
y = -3x - 2
-3
m = 7/8
Seven units up, 8 units over.
Identify the slope: y = -5/2 x - 3/4
m = -5/2
What is the slope and y-intercept?
1/2x - y = 6
slope = 1/2
y-intercept = -6
Your phone plan costs 10$ a month, plus $0.15 for every minute you call someone. Write and equation to represent your monthly costs using C for monthly cost and m for minutes spent calling.
C = 0.15m + 10
4x + y = 7
-4
m = -0.75.
3 units down, 4 units over.
Identify the y-intercept: y = 3/4x - 2
-2
What is the slope and y-intercept?
-5x - 2y = -14
slope = -5/2
y-intercept = 7
your mom gives you 15$ for every chore you help her with. She also gives you 50$ a month. Write an equation for how much money you make, using C for how many chores you do, and M for how much money you make.
-6x + 3y = 9
2
y = -9x + 3
9 units down, one unit over.
Write the equation in y = mx+b
y intercept = -1
points (2,4) and (3,6)
y = 2x -1
What is the slope and y-intercept?
-x - y = -1
slope = -1
y-intercept = 1
Write an equation to represent the following statement:
you double a number (x) and subtract 5.
y = 2x-5
