mathstudent55 · Answer

The x-intercept is where the graph crosses the x-axis. At that point, the y-coordinate is zero.
Let y = 0 and solve for x.

how do you solve

mathstudent55 · Answer

Here's the equation:
-1/2x-5y=-10 
Now replace y with 0:
$ -\dfrac{1}{2}x - 5y = 0$

$-\dfrac{1}{2}x - 5 \cdot 0 = -10 $

$-\dfrac{1}{2}x - 0 = -10 $

$-\dfrac{1}{2}x = -10 $

Since x in beiung multiplied by -1/2, multiply both sides by -2 to find x.
