Q. Line j has an equation of y+6=6(x−1). Line k is perpendicular to line j and passes through (8,−4). What is the equation of line k ?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 j: First, we need to find the slope of line j by putting its equation into slope-intercept form y=mx+b.y+6=6(x−1)y=6x−6−6y=6x−12The slope m of line j is 6.
Determine Slope of Line k: Since line k is perpendicular to line j, its slope will be the negative reciprocal of the slope of line j. The negative reciprocal of 6 is −61. So, the slope (m) of line k is −61.
Use Point-Slope Form: Now we have the slope of line k and a point (8,−4) through which it passes. We can use the point-slope form to find the equation of line k. The point-slope form is y−y1=m(x−x1), where m is the slope and (x1,y1) is the point.
Convert to Slope-Intercept Form: Plugging the slope and the point into the point-slope form, we get:y−(−4)=−61(x−8)y+4=−61x+68y+4=−61x+34
Convert to Slope-Intercept Form: Plugging the slope and the point into the point-slope form, we get:y−(−4)=−61(x−8)y+4=−61x+68y+4=−61x+34To get the equation into slope-intercept form, we need to isolate y:y=−61x+34−4y=−61x+34−312y=−61x−38
