How do you write an equation of a line given (0,4) & is parallel to y=3x-7?
To solve this problem, we'll need to use our friend the point slope formula. (You'll use this formula in more advanced math more often then you think!)
Point slope formula is:
If it's parallel to the line, then it must have an equal slope. The line is given in
Looking at our coordinates the x coordinate is 0 and the y coordinate is 4 so that gives us
Now we solve for y by distributing the 3 on the right side and adding 4 to both sides.
