Q. Line v has an equation of y=−910x−3. Perpendicular to line v is line w, which passes through the point (2,3). What is the equation of line w? 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 v: Determine the slope of line v.The equation of line v is given as y=−910x−3. The slope (m) of a line in the form y=mx+b is the coefficient of x. Therefore, the slope of line v is −910.
Find slope of line w: Find the slope of line w. Since line w is perpendicular to line v, its slope will be the negative reciprocal of the slope of line v. The negative reciprocal of −910 is 109.
Use point-slope form: Use the point-slope form to find the equation of line w. We have the slope of line w (109) and a point through which it passes (2,3). 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)=109(x−2).
Simplify to slope-intercept form: Simplify the equation to slope-intercept form.Starting with (y−3)=109(x−2), we distribute the slope on the right side:y−3=109×x−109×2y−3=109×x−1018Now, add 3 to both sides to solve for y:y=109×x−1018+3y=109×x−1018+1030y=109×x+1012Simplify the fraction1012 to 56:y−3=109×x−109×20
