Can you help me with a question? What is the equation of the blue line?
Artist 52 [7]

Answer:

y = -x - 1

Step-by-step explanation:

y = mx + b

<u>slope (m):</u> Since the line is going downhill, the slope will be negative

slope = rise / run

slope = 1 / 1

slope = 1

m = -1

<u>y - intercept (b):</u> this when x = 0, the line is crossing the vertical line (y-axis)

b = -1

so y = mx + b is

b = -1, m = -1

y = (-1)x + (-1)
