Q. Line r has an equation of y=76x+1. Line s includes the point (7,−7) and is perpendicular to line r. What is the equation of line s? Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Find Perpendicular Slope: Line r's slope is 76. Since line s is perpendicular to r, its slope is the negative reciprocal of 76, which is −67.
Calculate Y-Intercept: Using the point (7,−7) and the slope −67, plug into the equation y=mx+b to find b, the y-intercept of line s.−7=(−67)⋅7+b
Simplify Equation: Simplify the equation: −7=−649+b.
Solve for b: Add 649 to both sides to solve for b: b=−7+649.
Convert to Fraction: Convert −7 to a fraction with a denominator of 6: −7=−642.
Add Fractions: Now add −642 to 649 to get b: b=−642+649.
Final Equation: Simplify b: b=67.
Final Equation: Simplify b: b=67.The equation of line s in slope-intercept form is y=−67x+67.
