b. The statement is false.
ANSWER:
Study Guide and Review - Chapter 4
false, slope-intercept form
Write an equation of a line in slope-intercept form with the given slope and y-intercept. Then graph the
equation.
11. slope:−2, y-intercept: −9
SOLUTION:
is the y -intercept.
The slope-intercept form of a line is y = mx + b, where m is the slope, and b
To graph the equation, plot the y-intercept (0, −9). Then move down 2 units and right 1 unit. Plot the point. Draw a
line through the two points.
ANSWER:
y = −2x − 9
13. slope:
, y-intercept: −2
SOLUTION:
is the y -intercept.
The slope-intercept form of a line is y = mx + b, where m is the slope, and b
