Answer:

y-intercept: (0,6)

slope = -2

equation: y = -2x + 6  

Step-by-step explanation:

1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.

2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula m = \frac{y_2-y_1}{x_2-x_1}and solve:

m = \frac{0-6}{3-0}\\m = \frac{-6}{3}\\m =  -2

So, the slope is -2.

3) With the found information, use the slope-intercept formula y = mx + b to write the line's equation. Substitute values for the m and b.

m represents the slope, so substitute -2 in its place. b represents the y-intercept, so substitute 6 in its place. This gives the following equation:

y = -2x + 6

Can you help me with this question I rlly need it rn and please use the options it gives you thank you<3

Answer:  Choice C

Closed filled in circle at -3; shading to the right.

========================================================

Explanation:

Follow the steps shown below to isolate x. Note that the inequality sign flips when we divide both sides by a negative number.

-4x+8 \le 20\\\\-4x \le 20-8\\\\-4x \le 12\\\\x \ge 12/(-4)\\\\x \ge -3\\\\

Here's another way to isolate x

-4x+8 \le 20\\\\8 \le 20+4x\\\\4x+20 \ge 8\\\\4x \ge 8-20\\\\4x \ge -12\\\\x \ge -12/4\\\\x \ge -3\\\\

The inequality sign flip happens much earlier when we go from the format of A \le B to B \ge A  (in step 3)

The graph of this will have a closed filled in circle at -3, then shading to the right to describe all values -3 or larger.

This is why we go for choice C.
