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

Then, algebraically,

• an x-intercept is a point on the graph where y is zero, and
• a y-intercept is a point on the graph where x is zero.

More specifically,

• an x-intercept is a point in the equation where the y-value is zero, and
• a y-intercept is a point in the equation where the x-value is zero.

Graph the equation by using x and y-intercept method. First, find the x and y intercept from the equation and then plot the points on the grid and join then to complete the graph.

Find the x-intercept, plug in $y=0$in the equation.

$$\begin{gathered} 5x+2=−3 \\ 5x+2=−3\text{[Plugin}y=0] \\ 5x+2−2=−3−2 \\ 5x=−5 \\ \frac{5x}{5}=\frac{−5}{5} \\ x=−1 \end{gathered}$$

x-Intercept: $x=−1$

Find the y-intercept, plug in $x=0$in the equation.

$$\begin{gathered} 5x+2=−3 \\ 5\left(0\right)+2=−3\text{[Plugin}x=0] \\ 0 \\ y=0\text{[Sinceno}y\text{isintheequation}] \end{gathered}$$

y-Intercept:$y=0$

Graph the line $5x+2=−3$with x and y intercepts points are$\left(−1,0\right)$and $\left(0,0\right)$.

Thus, x and y intercepts are $x=−1$and $y=0$.
