WebTo find where y=1/2x+5 and the original line y=-2x intersect, set them equal to each other. Let y in both of the equations equal the same value. You are doing this because at the two lines' point of intersection, both lines will share the same x and y value. So, let y=1/2x+5 equal y=-2x. That means. -2x = 1/2x+5. mystery of the metro

Equation of a perpendicular line corbettmaths The … WebThe parallel line needs to have the same slope of 2. We can solve it by using the "point-slope" equation of a line: y − y1 = 2 (x − x1) And then put in the point (5,4): y − 4 = 2 (x − 5) That is an answer! But it might look better in y = mx + b form. Let's expand 2 (x − 5) and then rearrange: y − 4 = 2x − 10. WebTo determine if two lines are perpendicular, we need to multiply their gradients together. If the lines are perpendicular to each other, the product of their gradients will be -1. mystery of the megaflood answers
