Question

HELP ME I NEED HELP AND I DONT KNOW THE ANSWER

Answer 1

Check B

(-3,0) and (0,-3)

Find slope

• m=-3-0/0+3
• m=-3/3
• m=-1

It has y intercept (0,-3)

Check A

(3,0) and (0,3)

• m=3-0/0-3
• m=3/-3
• m=-1

Option A is correct

Answer 2

A

Explanation:

Positive slope: as the x-value increases, the y-value increases.

Negative slope: as the x-value increases, the y-value decreases.

The slope of the graph is -1

As it has a negative sign, the graph has a negative slope.

As the slope is -1, this means that for every 1 unit increase of the x-value, the y-value decreases by 1 unit.

The line passes through (0, 3)

When the x-value is zero, the line intercepts the y-axis.

Therefore, the line will intercept the y-axis when y = 3.

Therefore, the graph of the line that passes through (0, 3) and has a slope of -1 is option A.
