Q. The equation for line s can be written as y=−10x+45. Parallel to line s is line t, which passes through the point (−1,3). What is the equation of line t?
Find Slope of Line s: Determine the slope of line s.Line s has the equation y=−10x+45. The slope of a line in the slope-intercept formy=mx+b is the coefficient of x, which is m.The slope of line s is −10.
Determine Parallel Line Slope: Since line t is parallel to line s, it must have the same slope. Parallel lines have identical slopes. Therefore, the slope of line t is also −10.
Use Point-Slope Form: Use the point-slope form to find the equation of line t. 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 know the slope (m) is –10 and the point (x1,y1) is (–1,3).
Plug in Slope and Point: Plug the slope and point into the point-slope form to get the equation of line t.y−3=−10(x−(−1))y−3=−10(x+1)
Distribute and Simplify: Distribute the slope on the right side of the equation and simplify. y−3=−10x−10
Solve for y: Solve for y to put the equation in slope-intercept form.y=−10x−10+3y=−10x−7
