Question

What can you say about the two given equations of a line below ?
y= 2x+4
y= -1/2x+4

Answer 1

They’re linear and opposite inverses
Their y-intercepts are the same and their slopes are opposite inverses

Answer 2

y=2x+4

y=-1/2x+4

linear quations

both have the same y intercept (=4).

y=2x+4 is positive straight line, slope = 2

y=-1/2x+4 is negative straight line, slope=-1/2
