2) What is the equation of a line through the point (2,17) that has a slope of 7?
3) What is the equation of a line through the point (1,3) that has a slope of -2?
4) What is the equation of a line through the point (4,6) that has a slope of ½ ?
III (online)
Try each question then check your answers against the solutions at (www.mathwarehouse.com/lines4/)
1) What is the equation of a line through the point (2,3) that has a slope of ½ ?
2) If the slope of a line is 10 and the line goes through the point (3, 34), express the equation of
this line in slope-intercept form.
3) If the slope of a line is 3 and the line goes through the point (6,23), express the equation of this
line in slope-intercept form.
4) If the slope of a line is 0 and the line goes through the point (7,5), express the equation of this
line in slope-intercept form.
5) If the slope of a line is undefined and line goes through the point (-3, -13), express the equation
of this line in slope-intercept form.
Model Problem 1 Answer
1) What is the equation of a line with a slope of 3 that goes through
the point (2,8) ?
Step 1) substitute slope into equation
y = 3x +b
Step 2) substitute (2,8) into equation
8 = 3(2) +b
Step 3) solve for b
8=6+b
-6 -6
2=b
Step 4) substitute B into equation
y = 3x + 2
Model Problem 2 ANSWER
What is the equation of a line with a slope of 2 that goes through the
point (4 , 12) ?
Step 1) substitute slope into equation
y = 2x +b
Step 2) substitute (4,12 ) into equation
12 = 2(4) +b
Step 3) solve for b
12 = 8 + b
12  8  b
8  8
4b
Step 4) substitute B into equation
y = 2x + 4
Model Problem 3)
ANSWER
What is the equation of a line with a slope of 4 that goes through the
point (1,9) ?
Step 1) substitute slope into equation
y = 4x + b
Step 2) substitute (1,9) into equation
9 = 4(1) +b
Step 3) solve for b
9  4b
4  4
5b
Step 4) Insert B into equation
y = 4x + 5
