Answer 1

Answer on Question#37696 - , Math - Geometry

What is the $x$-intercept of the graph: $2x + 4y = -10$

Solution.

$$4y = -10 - 2x$$ $$y = -\frac{10}{4} - \frac{2}{4}x$$ $$y = -\frac{5}{2} - \frac{1}{2}x$$

$x$-intercept of graph it is value of $x$ when $y = 0$

On the plane

$$y = 0$$ $$0 = -\frac{5}{2} - \frac{1}{2}x$$ $$0 = -5 - x$$ $$5 = -x$$ $$x = -5$$

Answer: The $x$-intercept of the graph is -5.
