Q. What is the equation of the line that passes through the point (5,−5) and has a slope of −53 ?Answer:
Identify slope and point: Identify the slope m and the point (x1,y1) through which the line passes.The slope is given as m=−53, and the point is (5,−5).
Use point-slope form: Use the point-slope form of the equation of a line to plug in the values.The point-slope form is y−y1=m(x−x1).Here, y1=−5, x1=5, and m=−53.So, y−(−5)=−53(x−5).
Simplify equation: Simplify the equation to get it into slope-intercept formy=mx+b.y+5=−53x+53×5y+5=−53x+3
Subtract to solve for y: Subtract 5 from both sides to solve for y.y=−53x+3−5y=−53x−2
