Question

draw the graph of the linear equation 2 x minus y + 1 is equal to zero from the graph find the value of x if the graph passes through the points for and one by two

Answer 1

Solution

if x = 0, then 2(0) + y = 4

y = 4

if x = 1, then 2(1) + y = 4

y = 2

if x = 2, then 2(2) + y = 4

y = 0

The three pairings can now be displayed as the three ordered pairs

(0,4), (1,2), and (2,0)

or in the tabular forms
