Slope-Intercept Form
What is slope-intercept form?
y = mx + b
What is the slope of y=-4x+8 ?
slope is -4.
(The number in front of the x.)
Write the equation in slope intercept form with a slope of 1/4 and a y-intercept of -2.
y = 1/4x + -2 OR y = 1/4x - 2
Write the equation of the line represented by the table........
Slope= 12/1 = 12
y-intercept= 20
Line: y = 12x + 20
Write the equation of the line represented by the graph........
Slope= -3/1 = -3
y-intercept= 4
Line: y = -3x + 4
Which letter stands for the y-intercept of the line?
'b' stands for the y-intercept in y = mx + b
What is the y-intercept of y = 6x + 20?
The y-intercept is 20.
(It's the 'b'.)
Write the equation in slope intercept form with a slope of 0 and a y-intercept of -2.
y = -2
Write the equation of the line represented by the table........
Slope= 4/2 = 2
y-intercept= -1
Line: y = 2x + -1
Write the equation of the line represented by the graph........
Slope= 1/3
y-intercept= -6
Line: y = 1/3x + -6
What letter stands for the slope of the line?
'm' stands for this in y = mx + b
(Think of a mountain slope. It's the letter in front of the x.)
Name the slope and y-intercept of y = 4x - 3.
the slope= 4 and y-intercept = -3.
What is the slope between points (0, -4) and (2, 1)?
Put in a table: x y
0 -4
2 1
change y / change x = 5/2
How do you write a y-intercept 2 as a coordinate point?
(0, 2)
Name the slope and y-intercept of y = -1/5x
the slope is -1/5 and the y-intercept is 0.
Write the equation in slope intercept form with two pairs of (0,2) and (2,5)
y = 3/2x + 2
Which of the following coordinate points could be a y-intercept?
A. (3, 5) B. (0, -9) C. (4, 0) D. 3/5
B. (0, -9) could be a y-intercept because it's on the y-axis.
Name the slope and y-intercept of y = x - 8.
the slope is 1 and the y-intercept is -8
