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
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
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 equation of the line with slope 1 and
y-intercept -7 ?
y = x - 7
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
