Question 618001: 1)what is the equation of a line with a slope of 3 that goes through the point (2,8)?
2)what is the equation of a line with a slope of 2 that goes through the point (4,12)?
3)what is the equation of a line with a slope of 4 that goes through the point (1,9)?
4)what is the equation of a line through the point (2,5) that has a slope of 10?
5)what is the equation of a line through the point (2,17) that has a slope of 7?
6)what is the equation of a line through the point (1,3) that has a slope of -2?
7)what is the equation of a line through the point (4,6) that has a slope of 1/2?
8)what is the equation of a line through the point (2,3) that has a slope of 1/2?
9)if the slope of a line is 10 and the line goes through the point (3,34), express the equation of this line in the slope-intercept form.
10)if the slope of a line is 3 and the line goes through the point (6,23), express the equation of this line in the slope-intercept form.
11)if the slope of a line is 0 and the line goes through the point (5,5), express the equation of this line in the slope-intercept form.
12)if the slope of a line is undefined and the line goes through the point (-3,-13), express the equation of this line in the slope-intercept form.

You can put this solution on YOUR website! 1)what is the equation of a line with a slope of 3 that goes through the point (2,8)?
--------------------
Use y = mx + b and the point to find b
----
8 = 3*2 + b
b = 2
-----
The equation is
y = 3x + 2 in slope-intercept form
3x - y = -2 in standard form
----------------
The other problems are similar.
Do them the same way.
