Find an equation of the line through (3,5) and parallel to y = 3x -7. Write the equation using function notation
1 answer:
Given:
Equation of line is .
To find:
The equation of line which is parallel line to and passes through (3,5) in function notation.
Solution:
Slope intercept form of a line is
where, m is slope and b is y-intercept.
On comparing the equation with slope intercept form, we get
So, slope of given line is 3.
Slope of parallel lines are same. Thus, the slope of parallel line is also 3.
Point slope form of a line is
where, m is slope.
The parallel line passes through (3,5) with slope 3. So, the equation of line is
Add 5 on both sides.
Function notation of this equation is
Therefore, the equation equation in function notation is .

Move the decimal to the right (you go to the right since the exponent is positive, if the exponent was negative then you would move left) seven times, giving you 9,300,000 miles (for Earth). You then do the same with the next equation, giving you 140,000,000 miles (for Mars).
Finally, to find the official number of miles, you simply work the equation 140,000,000 - 9,300,000 .. giving you 130,700,000 miles.
If your teacher wants you to put it back into exponential form, then you first make the number into a decimal that is greater than one and less than ten.

Then, what you want to do is count all of the zeros as a single exponent, giving you 5, but we're not done yet. To get the correct answer, you have to also count the numbers until you reach the decimal. Remember to take out the zeros, because they're not really necessary anymore!
