How do you Complete the equation of the line through ( 3 and minus 1 ) ( 4 7 )?
Points: (3, -1) and (4, 7) Slope: 8 Equation: y = 8x-25
Is x plus y2 equals 25 a linear equation?
No, not if the y is squared. When graphed the equation will not form a straight line.
What is the slope of the line with equation 17x plus 23y equals 25?
-17/23 and the intercept is 25/23
Does it matter when adding square roots if the square root line is across the whole equation?
For example if the question was √36 + √25 and the other was√36 +25 but the square root line was across the whole equation would it change the answer? And what would be the answer for both of them?
What is the equation and its perpendicular bisector equation of the line joining the points of -7 -3 and -1 -4 on the Cartesian plane showing key stages of work?
The key stages of the work are the following:1) Find the slope for the line that joins the given points.2) Divide -1 by this slope to get the slope of the perpendicular line.3) Find the midpoint (calculate the averages of the x-coordinates and of the y-coordinates).4) Use the point-slope equation of the line to find a line with the desired slope, that goes through the desired point.Another Answer:-Points: (-7, -3) and (-1, -4)Mdpoint: (-4,-3.5)Slope: -1/6Perpendicular slope: 6Equation: 6y = -x-25 or as x+6y+25 = 0Perpendicular bisector equation: y = 6x+20.5 or as 6x-y+20.5 = 0
