Question

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of each equation.

$\left(2,-3\right)$, $y=4x-9$

Step-by-Step Solution

Answer

The required equation is represented by $y=4x-11$.

Step 1. Determine the slope of provided equation.

Take the help of the standard form $y=mx+c$ in which the representation of the slope is m so compare this equation with the provided equation. 

$m=4$

Step 2. Determine the required equation.

Take the help of obtained standard form represented by $y-y_1=m\left(x-x_1\right)$ in which the required values can be filled by using the obtained slope because both the lines are having a parallel relation so their slope will be the same and take provided point as it is in the form of $\left(x_1,y_1\right)$.

$\begin{array}{c}y-\left(-3\right)=4\left(x-2\right)\\ y+3=4x-8\\ y=4x-11\end{array}$

Step 3. Write the conclusion.

The obtained equation is $y=4x-11$ so it is the required equation.
