Question #f7c1b

Answer 1

2

Explanation:

The graphical concept of x- and y-intercepts is pretty simple. The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis.

`y = -4 +2*x`
`=> 2*x +(-1)*y =4`
`=> x/2 +(-1/4)*y = 1`
Which is in the form `x/a+y/b =1`
Hence, X intercept of the line is 2 unit

Alternative Solution

As said before,The x-intercepts are where the graph crosses the x-axis. Now where the graph crosses or interest X axis , the Y co-ordinate of the point is "zero"
So, we can find the X intercept by putting `Y =0` In the equation.

`y = -4 +2*x`
`=> 2*x -4 =0`
`=> x = 4/2 = 2`
