WebWhat is the slope of any line parallel to the y-axis? 2. Why doesn’t it make sense to talk about the slope of the line between the two points (2, 3) and (2,-1)? 3. Find an equation of the line perpendicular to the graph of y =-4 x + 10 and passing through (2, 2). 4. Find an equation of the line through (5, 3) and parallel to the line whose ... WebThe negative reciprocal of that slope is: m = −1 −4 = 1 4. So the perpendicular line will have a slope of 1/4: y − y 1 = (1/4) (x − x 1) And now we put in the point (7,2): y − 2 = (1/4) (x …

WebFeb 24, 2024 · Worked-out Examples on Equation of y-axis and Equation of a line parallel to the y-axis. 1. Write the equation of a line parallel to y-axis and passing through the point (−2,−4). Solution: As we know that … WebIf you assume they are on the original line, then you would get the wrong value for y intercept. Lets try: say y = 2x + 3 and you want a perpendicular that goes through (-2,4) Rather than point slope, I will use the slope intercept equation and substitute. y = =1/2 x + b, so 4 = -1/2 (-2) + b, 4 = 1 + b, b = 3 and your perpendicular equation is ... datatable operator

We know that slope = change in y / change in x In the above … WebHence, the equation of a straight line parallel to y-axis at a distance a from it is x = a. The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it. Let P (x, y) be any point on the y-axis. Then … datatable pagination color change
