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?Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Find Slope of Line v: Determine the slope of line v. Line v has an equation of y=−51x+9. The slope-intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept. Therefore, the slope of line v is −51.
Determine Parallel Slope: Since line w is parallel to line v, it must have the same slope. Parallel lines have the same slope. Therefore, the slope of line w is also −51.
Calculate Y-Intercept of Line w: Use the point (−10,1) and the slope −51 to find the y-intercept (b) of line w.We can use the point-slope form of the equation of a line, which is y−y1=m(x−x1), where (x1,y1) is a point on the line and m is the slope. Plugging in the point (−10,1) and the slope −51, we get:1−y1=−51(x−(−10))1−y1=−51(x+10)Now we need to solve for −510, which is the y-intercept.
Solve for Y-Intercept: Solve for the y-intercept b of line w.1=−51(−10)+b1=2+bSubtract 2 from both sides to isolate b:1−2=b−1=bThe y-intercept of line w is −1.
Write Equation of Line w: Write the equation of line w in slope-intercept form.We have the slope m=−51 and the y-intercept b=−1. The slope-intercept form is y=mx+b. Substituting the values we have:y=−51x−1This is the equation of line w in slope-intercept form.
