Transcript text: Write the slope-intercept form of an equation of the line that passes through the given point and is parallel to the graph of each equation.
5. $(3,2), y=x+5$
6. $(-2,5), y=-4 x+2$
Solution
Solution Steps
Step 1: Identify the Slope of the Given Lines
For the first line \( y = x + 5 \), the slope \( m_1 \) is \( 1 \).
For the second line \( y = -4x + 2 \), the slope \( m_2 \) is \( -4 \).
Step 2: Use the Point-Slope Form for the First Line
Using the point \( (3, 2) \) and the slope \( m_1 = 1 \), we apply the point-slope form:
\[
y - y_1 = m(x - x_1)
\]
Substituting the values:
\[
y - 2 = 1(x - 3)
\]
Step 3: Convert to Slope-Intercept Form for the First Line
Rearranging the equation:
\[
y - 2 = x - 3 \implies y = x - 1
\]
Thus, the slope-intercept form for the first line is \( y = 1x - 1 \).
Step 4: Use the Point-Slope Form for the Second Line
Using the point \( (-2, 5) \) and the slope \( m_2 = -4 \), we apply the point-slope form:
\[
y - y_1 = m(x - x_1)
\]
Substituting the values:
\[
y - 5 = -4(x + 2)
\]
Step 5: Convert to Slope-Intercept Form for the Second Line
Rearranging the equation:
\[
y - 5 = -4x - 8 \implies y = -4x - 3
\]
Thus, the slope-intercept form for the second line is \( y = -4x - 3 \).
Final Answer
For the first line: \( \boxed{y = x - 1} \)
For the second line: \( \boxed{y = -4x - 3} \)
