This form needed. Y = mX + c2X + 8Y = 408Y = - 2X + 40Y = - 1/4 + 5-----------------------zero out the Y- 1/4X + 5 = 0- 1/4X = - 5X = 20-------------------your X intercept
7x + 8y
To determine slope and Y intercept, solve the equation for y... 5x - 8y + 64 = 0 -8y = -5x - 64 8y = 5x + 64 y = 5/8x + 8 ... now that you have the equation in the form y = mx + b, you can easily see that the slope is 5/8, and the Y intercept is 8.
(i) <- first part 8y+7-7y = 6+4 8y-7y = 6+4-7 y = 3 (ii) <- second part, put the value of 'y' that you found where y is in the question. 8(3) + 7 - 7(3) = 6+4 24 + 7 - 21 = 10 31-21 = 10 10 = 10 both sides equal the same thing therefore this equation is proved.
The given expression can be simplified to: x-5y
