20 POINTS AND BRAINLIEST

d. y = -3x -2

Step-by-step explanation:

Given S( 4, 10 ) and T( -2, -8 ) are on a line.

General form of a line is y = ax + b

With :

a = incline or gradient

b = intercept with the y-axis

The gradient can be found by the differences in x-coordinates of S and T divided by differences in y-coordinates of S and T.

a = ( 4 - -2) / (10 - -8)

a = ( 4 + 2) / (10 + 8)

a = 6 / 18

a = 1/3

The question is what is the line which is perpendicular to this line.

General form of a line is y = ax + b

perpendicular to 1/3 = - 3/1 so a = -3

All given lines in answers a, b , c and d have a value for b of -2.

So that line would be y = -3x -2

So the correct answer is d.

Extra:

If you want to find the value of b, of the line through S and T, then you can substitute one of the given points in the line.

y = 1/3x + b

Substitute T(-2, -8)

-8 = (1 * -2)/3 + b

b = -8 + 2/3

the full equation of this line is

y = 1/3x + 8 2/3

y = 1/3x + 8,666666666666666666666

Sometimes written as y = 1/3x + 8,(6)

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
