what do the m and b stand for in y = mx+b?
m: Slope
b: y - intercept
Graph y = -3(x + 4)
Look at Mr. Goedert's graph
How is standard form written? ex: y = mx+b
ax + by = c
How can you tell if a two lines are parallel?
Same Slope
What is Mr. Goedert's dog's name?
Echo
Graph y = -1/2 x +3
look at graph
Graph y = -3(x-2) + 4
Look at Mr. Goedert's graph
switch from standard from to y = -2x + 6
2x + y = 6
How can you tell if two lines are perpendicular?

If a line has a slope of 5 and passes through (-5, 8) what is the equation in slope intercept form?
y = 5x +33
Switch to slope intercept form
y= 1/2 (x - 12) + 3
y = 1/2 x-3
Switch from slope intercept form to standard form.
y = 3/4 x + 8
3x-4y=-32
Write a line that is parallel to y = 3x - 5
any line with y = 3x + b where b does not equal -5
Spiderman lol
State the lines that passes through point (-5, 4) and (-3, -2)
y = -3x + 11
A ski lift on a mountain passes through the point (2, 500) and (4, 800) , where x is the distance in miles from the base of the mountain and y is the elevation in feet.
Write the equation of the lift’s path in h–k (point-slope) form.
y = 150 (x-4) + 800 and y = 150 (x-2) +500
A student spends 30 minutes reading each chapter of a novel and 20 minutes writing each essay. If the total time spent is 4 hours write the equation in standard form. Find the x and y intercepts
30x + 20y = 240
x=8
y=12
Are the following lines parallel or perpendicular.
y = -3x +5 and x - 3y = 15
Perpendicular
Who is Mr. Goedert's favorite rapper

Test Review #5
y = -6x + 24
x=-4
Number 10 Test Review
y = 2/7 (x - 28) + 14.99 or y = 2/7 (x-56) + 22.99
6.99
Switch from hk to standard form.
y = -3(x - 5) + 3
3x + y = 18
Determine if the following equations are parallel, perpendicular, or neither?
3x + 6y = 18 and 12x - 2y = 36
Perpendicular
