Q. The equation for line v can be written as y=−79x−5. Line w, which is perpendicular to line v, includes the point (9,6). 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=−79x−5. The slope (m) of a line in the form y=mx+b is the coefficient of x. Therefore, the slope of line v is −79.
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 −79 is 97.
Use point-slope form: Use the point-slope form to find the equation of line w. We have the slope of line w (97) and a point through which it passes (9,6). 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−6)=97(x−9).
Simplify to slope-intercept form: Simplify the equation to slope-intercept form.Starting with (y−6)=97(x−9), we distribute the slope on the right side:y−6=97×x−97×9y−6=97×x−7To get y by itself, add 6 to both sides:y=97×x−7+6y=97×x−1
