Answer:
M= the slope. ( it would be the first one)
Step-by-step explanation:
In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis. What is the coordinate on the y-axis where the graph of y = 2x + 3 crosses y-axis?
