write an equation in standard form that:
1) passes though (7,2) and parallel to x+y=6
2) passes through (1,9) and is perpendicular to 2x-5y=8
Have you made any attempt at these questions? How far have you got?
Both of these need to be in the form y = mx + c (or whatever symbols you're using for "gradient" and "y-intersection" - m and c are what I'm using, respectively).
So here are two further sub-questions that will get you started on the first question:
i) What is the gradient (m in the equation above) of the first line?
If you can answer this, you'll have the m in the equation. Then:
ii) What does c have to be so that y = 2 when x = 7?
Get back with any thoughts/answers/guesses (:P) you have for these.
can you plese help me,im a fith grader whom needs help 13kayduz
