Question

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

Answer 1

Answer:

-1.154

Step-by-step 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

$13x=-15\\\\x=-\frac{15}{13}\\\\x=-1.154$

Therefore, x-intercept is -1.154

Answer 2

Answer:

$-\frac{15}{13}$

Step-by-step explanation:

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

$13x+y=-15$

$13x+0=-15$

$13x=-15$

$x=-\frac{15}{13}$
