Finding m & b
Identify the slope and y-intercept of the equation y=5x+16
Slope= 5
Y-Intercept= 16
Convert the equation to slope-intercept form.
y + 4 = 16x
y = 16x - 4
or
y = 16x + -4
Graph the two points to find the slope.
(-3, 1) and (7, -4)
m = -5/10
Find the slope using the slope formula:
(5, 8) and (8, 10)
m = 2/3
State the slope and y-intercept
y = 1/2 x +5
m = 1/2
b = 5
Convert the equation to slope-intercept form.
y + 4 = 3x
y = 3x - 4
or
y = 3x + -4
Graph the two points to find the slope.
(4, 1) and (6, -2)
m = -3/2
Find the slope using the slope formula:
(-2, 3) and (1, 4)
m = 1/3
State the slope and y-intercept from the equation:
y = 2x - 8
m = 2
b= -8
Convert the equation to slope-intercept form.
y - 5 = 1/2 x
y = 1/2 x + 5
Graph the two points to find the slope.
(3, -1) and (-2, 5)
slope = -6/5
Find the slope using the slope formula:
(0, -6) and (2, 3)
m = -9/2
State the slope and y-intercept
y = x + 10
m = 1
b = 10
Convert the equation to slope-intercept form.
y - 4 = 3x
y = 3x + 4
Graph the two points to find the slope. Simplify it.
(-4, -2) and (1, 3)
m = 1
from
m = 5/5
Find the slope using the slope formula:
(-4, 8) and (-2, 11)
m = 3/2
Identify the slope and y-intercept of the equation.
y = -x - 2
m= -1
b= -2
Convert the equation to slope-intercept form.
Careful with this one.
y - 2x = 5
y = 2x + 5
from y = 5 + 2x
Graph the two points to find the slope.
(2, 3) and (-4, 3)
m = 0
m = 0/6
Find the slope using the slope formula:
(3, -4) and (4, -5)
m = -1
Identify the slope and y-intercept of the equation.
y=7
Slope= 0
Y-intercept= 7
Convert the equation to slope-intercept form.
y + 4x = 10
y = -4x + 10
from y = 10 - 4x
Graph the two points to find the slope.
(-2, -3) and (-2, -5)
Undefined
m = -2/0
Find the slope using the slope formula:
Simplify it
(-2, -1) and (-4, -7)
m = 3
from
m = -6/-2 = 6/2 = 3
