1 answer:

4 0

Y - 2x = 8 . . . . . . . . (1)
16 + 4x = 2y . . . . . .(2)
From (1), y = 8 + 2x
substituting for y into (2), we have
16 + 4x = 2(8 + 2x) = 16 + 4x
0 = 0
Therefore, there are an infinite number of solutions

function : y = (-x) - 6

Find x-intercept :

(-x) - 6 = 0

(-x) = 6

x = -6

Find y-intercept :

y = (-0) - 6

y = -6

mark these two points on both the axis and draw a straight linear graph.

passes coordinates : (0, -6), (-6, 0)
