Write the equation of a line that is PARALLEL to 5x + 4y = -10 and goes through the point (4, 2). Show ALL your work (include all steps that you must go through to get the final equation).

4 marks.

Hint: find the slope first (m value) and then find the b value.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the square root of what number? if you add that, then someone will probably answer the question.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
