Math Problem Statement
write an equation for the line that passes thorught (8, 2) and is parallel to the graph of y + 3/4x + 2
Solution
The given equation of the line is:
To find the slope of this line, rearrange it into the slope-intercept form ():
Here, the slope () is .
A line parallel to this one will have the same slope, . Using the point-slope form of a line equation:
where and , substitute the values:
Simplify the equation:
Thus, the equation of the line is:
