Question

What is the x-intercept of the line with this equation 13x+y=−15 ? Enter your answer in the box.

Answer 1

`-(15)/(13)`

Explanation:

To solve the x-intercept, we plug in 0 for y and solve.

`13x+y=-15`

`13x+0=-15`

`13x=-15`

`x=-(15)/(13)`

Answer 2

-1.154

Explanation:

The equation of line is
`13x+y=-15`

x-intercept is the point where line intersects the x axis. At x-axis, the y-coordinate is zero.

Hence, for x-intercept, plug y=0 in the given equation

`13x+0=-15`

Solve the equation for x

`13x=-15\\\\x=-(15)/(13)\\\\x=-1.154`

Therefore, x-intercept is -1.154
