What is the perpendicular slope to 6/-3

IRISSAK [1]

Answer:

Perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Step-by-step explanation:

Given:

Let the perpendicular slope be x.

The given slope is $\frac{6}{-3}$

For perpendicular slopes, the product of the slopes is equal to -1.

Therefore, $x\times \frac{6}{-3}=-1\\-\frac{6}{3}x=-1\\6x=3\\x=\frac{3}{6}=\frac{1}{2}$

Therefore, the perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

For the straight line defined by the points (2,55) and (4, 87), determine the slope (m) and y-intercept?

mamaluj [8]

Answer:

Slope(m) = 16

Y intercept (c) = 23

Step-by-step explanation:

Given:

Points : (x1, y1) = (2, 55)

(x2, y2) = (4, 87)

Using two point form to calculate slope:

$m = \frac{y2-y1}{x2-x1}$

$m = \frac{87-55}{4-2}$

m = 16

To find y intercept:

Take any one point ans slope :

Using slope point formula:

y = mx + c

87 = 16(4) + c

Solving for c:

c = 23
