x=4, y=9 (4,9)
x=7 and y=4
-4
This means that 2y - 3 = 2y + 4 which is not possible.
8x + 2y = 1 Rearrange in to straight line form 'y = mx + c'. 'm' is the slope/gradient of the line 'c' is the y intersept. Hence 2y = -8x + 1 y = -4x + 1/2 So slope is '-4'. and y-intercept is '1/2' 4
x=4, y=9 (4,9)
x=7 and y=4
-4
x = -8, y = 10
the slope of the line is -4
-4
-4
This means that 2y - 3 = 2y + 4 which is not possible.
8x + 2y = 1 Rearrange in to straight line form 'y = mx + c'. 'm' is the slope/gradient of the line 'c' is the y intersept. Hence 2y = -8x + 1 y = -4x + 1/2 So slope is '-4'. and y-intercept is '1/2' 4
16X - 2Y = 4- 2Y = - 16X + 4Y = 8X - 2---------------m(slope) = 8===========
4y + 4 = 2y + 12Subtract 2y from each side of the equation:2y + 4 = 12Subtract 4 from each side:2y = 8Divide each side by 2:y = 4
Rewrite the equation in the form y = mx + c and then m is the slope. Thus: 2y = -8x + 5 and then y = -4x + 5/2 So the slope is the coefficient of x, which is -4.
