Question

On the grid draw the graph of x + 2y =7

Answer 1

See attachment for graph

Explanation:

Given

`x + 2y = 7`

Required

Draw the graph

First, we identify at least 2 possible values of x and y

Let
`x = 1`

Solve for y

`x + 2y = 7`

`1 + 2y = 7`

`2y = 6`

`y = 3`

So, a point is:
`(1,3)`

Let
`x = 3`

Solve for y

`x + 2y = 7`

`3 + 2y = 7`

`2y = 7 -3`

`2y = 4`

`y = 2`

So, another point is:
`(3,2)`

Plot
`(1,3)` and
`(3,2)` on the graph, then draw a straight line through both points
