Q. The equation for line u can be written as y=−49x+1. Line v, which is perpendicular to line u, includes the point (−3,2). What is the equation of line v?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 u: Determine the slope of line u. The equation of line u is given as y=−49x+1. The slope (m) of a line in the slope-intercept form y=mx+b is the coefficient of x. Therefore, the slope of line u is −49.
Find slope of line v: Find the slope of line v. Since line v is perpendicular to line u, its slope will be the negative reciprocal of the slope of line u. The negative reciprocal of −49 is 94. Therefore, the slope of line v is 94.
Use point-slope form: Use the point-slope form to find the equation of line v. We have the slope of line v (94) and a point through which it passes (−3,2). 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−2)=94(x−(−3)).
Simplify equation of line v: Simplify the equation of line v.Starting with (y−2)=94(x+3), we distribute the slope on the right side:y−2=94×x+94×3y−2=94×x+34Now, we add 2 to both sides to solve for y:y=94×x+34+2
Convert constant term: Convert the constant term to a common denominator and combine terms.The common denominator for 34 and 2 is 3. So we convert 2 to 36:y=94×x+34+36y=94×x+(34+6)y=94×x+310This is the equation of line v in slope-intercept form.
