Answers

Answer:

x < 5

Step-by-step explanation:

Hi,

If you have a line under the < or > sign, it means x can be less than OR EQUAL TO, since x has to be less than 5, neither of those signs can work. Now, < means less than and > means greater than. For this, x < 5 is the correct answer because we know that x has to be less than 5.

Answers

Answer:

-3

Step-by-step explanation:

(6, 4) and (8, -2)

Slope:

m=(y2-y1)/(x2-x1)

m=( -2 -4)/(8-6)

m = (-6)/2

m = -3

Answer:

-3

Step-by-step explanation:

(6, 4) and (8, -2)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-2 - 4) / (8 - 6)

Simplify the parentheses.

= (-6) / (2)

Simplify the fraction.

-6/2

= -3

This is your slope.
