Q. The equation for line c can be written as y=43x−2. Line d, which is perpendicular to line c, includes the point (6,−3). What is the equation of line d?Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Determine slope of line c: Determine the slope of line c.The equation of line c is given as y=43x−2. The slope (m) of a line in the slope-intercept form y=mx+b is the coefficient of x. Therefore, the slope of line c is 43.
Find slope of line d: Find the slope of line d, which is perpendicular to line c. The slope of lines that are perpendicular to each other are opposite reciprocals. The opposite reciprocal of 43 is −34. Therefore, the slope of line d is −34.
Use point-slope form: Use the point-slope form to find the equation of line d. We have the slope of line d−34 and a point that line d passes through (6,−3). The point-slope form of a line is (y−y1)=m(x−x1), where m is the slope and (x1,y1) is the point on the line. Plugging in the values, we get (y−(−3))=−34(x−6).
Simplify equation to slope-intercept form: Simplify the equation of line d to slope-intercept form. Starting with (y+3)=−34(x−6), distribute the slope on the right side: y+3=−34×x+34×6y+3=−34×x+8 Now, subtract 3 from both sides to solve for y: y=−34×x+8−3y=−34×x+5
