Answer
a) $(-15,0)$
b) $(0,-10)$
c) $x=15$
d) $x=7.5$
e) $y\approx 3$
Work Step by Step
a) The $x$-intercept is the value of $x$ corresponding to $y=0$: -15. As a point, it can be written as
$(-15,0)$
b) The $y$-intercept is the value of $y$ corresponding to $x=0$: -10. As a point, it can be written as
$(0,-10)$
c) The value of $x$ that results in $y=-20$ is 15 because the point $(15,-20)$ belongs to the graph.
$x=15$
d) The value of $x$ that results in $y=-15$ is 7.5 because the point $(7.5,-15)$ belongs to the graph.
$x=7.5$
e) The value of $y$ when $x=-10$ is around 3 because the point $(-10,3)$ belongs to the graph.
$y\approx 3$
