CD: (-5,3) and (-4,6)
Perpendicular
What form of equations do we use for lines?
y = mx + b or slope intercept form.
Tell whether the following equations are parallel, perpendicular, or neither.
3x-y =2 and 12x -4x = 4
Parallel
Write an equation for a vertical line through the point (-3, 3)
x = -3
Write an equation passing through the point that is parallel to the given equation.
(8,3): y= -1/4x + 7
y= -1/4x + 5
Write an equation for a line with the following slope and points.
m = 2/3 and (0, -2), (3, 0)
y = 2/3x - 2
Passing through (-2,8) and perpendicular to y=2x+ 5
y= -1/2x + 7
Write an equation for a line with the following two points. Find the slope and y intercept. (15, -10) (5, 10)
slope = -2 y intercept = 20
y = -2x + 20
Passing through (-2,-11) and perpendicular to
x + 4y= 8
y= 4x -3
The amount y(in dollars) of money you have left after playing x games at a carnival is y = -0.75x + 10. How much money do you have after playing eight games? Graph the equation and show your explanation.
y = -0.75(8) + 10 y = -6 + 10 y = 4 $4 dollars left after playing 8 games. Graph should begin at (0, 10) on the y-axis and move down three and four to the right.
