Math Problem Statement
Write an equation of the line containing the given point and parallel to the given line. Express your answer in the form
yequals=mxplus+b.
(negative 2−2,22);
88xequals=99yplus+5
Solution
To find the equation of the line that passes through the point and is parallel to the line , follow these steps:
Step 1: Rewrite the given line in slope-intercept form ()
Start by converting the given equation into slope-intercept form:
Subtract 5 from both sides to isolate the term:
Now, divide both sides by 9 to solve for :
This gives us the slope .
Step 2: Use the point-slope form to find the equation of the new line
Since the new line is parallel to the given line, it will have the same slope . We can use the point-slope form of the line equation, which is:
Where . Substitute the values:
Step 3: Simplify to slope-intercept form ()
Distribute the slope on the right side:
Now, add 2 to both sides to solve for (remember that 2 is equivalent to in terms of ninths):
Final Answer:
The equation of the line in the form is:
