OK, so to do this one, we need to figure out the slope first.
So two X -, 5 Y equal 4.
We're going to solve for Y so we can put it in slope intercept
form, subtract the 2X and divide by -5 a -2 / A negative 5 is
going to give us a positive 2/5.
So we're going to get Y equal 2/5 X -4 fifths.
Now the slope here is 2/5, and on this problem we want it to be
parallel.
So we're going to have Y minus our given point.
We're going to use point slope form y - -4 equal 2 fifths X -
-7.
So y + 4 equal 2 fifths X + 7.
Now the directions say we want to put it in Y equal MX plus B4.
So we're going to distribute out that 2 fifths 2/5 X.
If I have 2/5 * 7, that seven is understood over one.
So y + 4 equal to fifths, X + 14 fifths.
Multiply the numerators.
Multiply the denominator.
We're going to subtract the four to the other side.
So 2 fifths X + 14 fifths -4 we need to turn that four into
fifths.
Y equal 2 fifths X + 14 fifths that 4 / 1.
Think of 4 / 1.
How many fifths when we multiply the one by five?
So we've got to multiply the four also by 5 S 4 / 1 is really
20 fifths.
Once we get the same denominators.
If we're adding or subtracting, we just combine the numerators.
So Y = 2 fifths, X -, 6 fifths.
That's 5 - 6 fifths.
