Q. The equation for line s can be written as y=−10x+45. Parallel to line 5 is line t, which passes through the point (−1,3). What is the equation of line 1 ?
Determine slope of line s: Determine the slope of line s. The equation of line s is given as y=−10x+45. The slope of a line in the form y=mx+b is m, where m is the coefficient of x. The slope of line s is −10.
Find slope of line t: 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 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)
Simplify equation: Simplify the equation to get it into slope-intercept form, y=mx+b.y−3=−10x−10y=−10x−10+3y=−10x−7
