Question

Draw the graph of the equation x - y = 4
Answer the following using graph paper,
(1) Find the value of y, if x = 7 from the graph
(ii) Write the coordinate of the point where the graph intersect on x - asis,​

Answer 1

R.E.F image

x+y=7

Putting x=0

0+y=7

y=7, so (0,7)

Putting y=0

x+0=7

x=7 so (7,0)
