# Algebra I Ch 5 Slope

### Equations of lines, slope, graphs, y-intercept, parallel and perpendicular lines

Write an equation in slope intercept form given the following: m = 2, b = -6 y = 2x - 6
Write an equation in slope intercept form given the following: m = -7/5, b = 8 y = -7/5x + 8
Write an equation in slope intercept form given the following. m = 2/3, b = -11 y = 2/3x - 11
Write the equation of a line that has the given slope and passes through the point: m = 5; (-2,-3) y = 5x + 7
Write the equation of a line that has the given slope and passes through the point: m = -2/3; (9,-6) y = -2/3x + 0
Write the equation of a line that passes through the given points: (-5,5) and (1,-1) y = -1x + 0
Write the equation of a line that passes through the given points. (-4,-9) and (-8,0) y = -9/4x - 18
Identify the slope and y-intercept. y = 2/5x + 8 m = 2/5 b = 8
Identify the slope and y-intercept. y = 12x - 1/7 m = 12 b = -1/7
Identify the slope and y-intercept. y = 6/7x m = 6/7 b = 0
Identify the slope and y-intercept. y = 3 m = 0 b = 3
Identify the slope and y-intercept. y = 5 + 3/4x m = 3/4 b = 5
Identify the slope and y-intercept. x = 13 m = undefined b =
rise over run = slope
line goes up as you move from left to right positive
line goes down as you move from left to right negative
line remains flat as you go from left to right zero slope
vertical lines slope undefined
when two lines are parallel, their slopes are __ equal
when two lines are perpendicular, their lines are __ reciprocals with opposite signs
what is the slope for a line with this equation? y = 7 zero
The equation of a line y =-3 could be rewritten as __ to better see the slope y = 0x - 3
x=4 is a __ vertical line
