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
(1, 1)
8x+2y=4x=-y/4+0.5y=-4x+2
x=7 and y=4
x=4, y=9 (4,9)
-4
no its not a solution
Solving by the elimination method: x = 7 and y = 2
x = -8, y = 10
the slope of the line is -4
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
x=1, y=1
-4
