color(blue)("x-intercept" = -5/2

#### Explanation:

The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis.

In the same way, the x-axis is also the line "y = 0".

Given : $y = 2 x + 5$

For getting x intercept, make $y = 0$ in the given equation.

$2 x + 5 = 0$

$2 x = - 5$ or color(blue)("x-intercept" = -5/2

Similarly, $\text{y- intercept is obtained by making } x = 0$

$y = 0 + 5 = 5$
