Determine the equation of the line that passes through the point (4,6) and is parallel to the line 8 y - 24 x = 7.
now what i have to choose from are
3 = y -6 / x - 4
y = 3x - 6
3 = x - 4 / y - 6
y = 3x + 6
y = 5

Put your parallel line in slope-intercept form.
Then y = 3x+7/8. This tells us the slope of the line is 3. This get rid of all but two choices.
If the line you want goes through (4,6), the intercept of the line (call it b) can be found. Its slope is known to be 3. And 6 = (3)(4) + b, and b= -6.
The line is y = 3x-6, your second choice.

First, we note that the required slope is 24/8 = 3. So we need c such that y = 3x + c given that x = 4 and y = 6. 6 = 3(4) + c, so c = -6 and the final result is the second choice.

Your solution is y = 3x - 6
