The grid shows a line L. 53 4 3- 5 -4 -2 1 10 1 2- -3- 4 (a) Find the equation of line L. Give your answer in the form y = mx + c. Y = mx +c m= = = 4=-4x+2 C=2 y= -2x+2 [2]

If possible, write -3 – a – 2x? as a linear combination of 2 + x + x?, 2 + 2x + x² and 3 + 3x + 2x2. Otherwise, enter DNE in all answer blanks. -3 - a – 2x? = (2 +x+ a?)+ (2 + 2x + a?)+ (3 + 3x + 2a?).

If possible, write -1- 12x - 8x² as a linear combination of -x-x², 2x + x² and 2x1 + x². Otherwise, enter DNE in all answer blanks. (-x-x²)+ -1-12x8x² (2x − 1 + x²). = (2x + x²)+

Subtract. (6x - 2x? + 5x- 8) - (4x° - 4x? - 3x + 2) (6x° - 2x? + 5x - 8) - (4x³ - 4x² - 3x +2) = D (Simplify your answer. Use integers or fractions for any numbers in the expression.)

If possible, write -6- 19x - 11x² as a linear combination of -1 - x - x², 1+ 2x + x² and -1 -3x - 2x². Otherwise, enter DNE in all answer blanks. (-1- x - x²)+ (1 + 2x + x²)+ -619x11x² = (-1-3x - 2x²).

I need to simplify

4x+8y=24 2.) 6x–4y=-10

12y+x=-3y+5x-6 Put in standard form. o bields

(a + 5) = 49 x +5 2.

Write an equation in the form y=mx+b for the following table: x y -10 -82 -8 -64 -6 -46 -4 -28 -2 -10 0 8 2 26 4 44 y= ___x+___
