Question

Graph y = x + 4. this is a khan academy question

Answer 1

The graph is a diagonal line passing through the point (0, 4).

How to plot linear equation.

A linear equation is a mathematical expression involving variables raised to the power of 1, producing a straight-line graph.

Let's create a table with x and y values to plot points for the equation y = x +4

Let's plot the points on a coordinate plane.

The graph of the function y = x + 4 is a straight line with a slope of 1, meaning it rises one unit for every one unit to the right.

The y-intercept is at (0, 4), and the line extends infinitely in both directions. The graph is a diagonal line passing through the point (0, 4).

Answer 2

Given function:

`y=x+4`

We will plugin some random values for
`x` to evaluate
`y` and thus find out the points in the form
`(x,y)` to be plotted on graph.

`x`
`y=x+4`
`(x,y)`

`0`
`0+4=4`
`(0,4)`

`1`
`1+4=5`
`(1,5)`

`2`
`2+4=6`
`(2,6)`

We have got 3 points of the line
`y=x+4` to plot on the graph. After plotting the points, we will join them and extend either side to infinity to get the line.
