if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form

Convert the equation 2y = 5x - 4 into standard form then y = 2.5x - 2.

Two straight lines are perpendicular if the product of their gradients is -1.

Let the equation of the perpendicular line by y = mx + b. Then, 2.5m = -1 : m = -1/2.5

The y intercept occurs when x = 0. Then -3 = 0 + bc : b = -3

The equation of the perpendicular line is y = -1/2.5x -3 or 5y = -2x -15

Ordered pairs are not specified.

if it is like (0,5),(0,1),(0,0),.... then we may find the answer, which then shows the family of different lines according to ordered pairs.

type the equation that shows the relationship between the variables in this chart.

X = 135 and y = 15

y equals -1/3x plus 4/3

No.

A point, in two dimensional space, is defined as an ordered pair.

If y varies directly as x and y is 18 when x is 24, then y is always three fourths of x. So if y is 15, then x is 20.

If: 12 = 2y+x then y = -1/2x+6

So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines

(f+g)(x)=8x^2+4x-4
