Q. Line v has an equation of y=−51x+9. Line w includes the point (−10,1) and is parallel to line v. What is the equation of line w?
Determine slope of line v: Determine the slope of line v.Line v has the equation y=−51x+9. The slope of a line in the form y=mx+b is m, where m is the coefficient of x.The slope of line v is −51.
Find slope of line w: Since line w is parallel to line v, it must have the same slope.The slope of line w is therefore also −51.
Use point-slope form: Use the point-slope form to find the equation of line w. The point-slope form of a line is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line. We have the point (−10,1) and the slope −51.
Substitute slope and point: Substitute the slope and the point into the point-slope form.Using the point (−10,1) and the slope −51, the equation becomes:y−1=−51(x−(−10))y−1=−51(x+10)
Simplify equation: Simplify the equation to get it into slope-intercept form, y=mx+b.y−1=−51x−51(10)y−1=−51x−2y=−51x−2+1y=−51x−1
