Q. Line j has an equation of y=−79x+710. Line k is parallel to line j and passes through (−4,4). 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: Determine the slope of line j. Line j has an equation of y=−79x+710. The slope of line j is the coefficient of x, which is −79.
Determine Slope of Line k: Since line k is parallel to line j, it will have the same slope. The slope of line k is therefore also −79.
Use Point-Slope Form: Use the point-slope form to find the equation of line k. Line k passes through the point (−4,4) and has a slope of −79. The point-slope form of the equation of a line is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line.
Substitute Slope and Point: Substitute the slope and the point into the point-slope form.Using the point (−4,4) and the slope −79, the equation becomes:y−4=−79(x−(−4))
Simplify the Equation: Simplify the equation.y−4=−79(x+4)y−4=−79x−79⋅4y−4=−79x−736
Solve for y: Solve for y to put the equation in slope-intercept form.y=−79x−736+4y=−79x−736+728y=−79x−78
