The Deep Dive
To write the equation of a line in slope-intercept form (y = mx + b), we start with the given slope \( m = 2 \). Next, we can substitute the slope into the equation, leaving the y-intercept \( b \) to be determined. Now, let's check which of the options fits this equation. The y-intercept is where the line crosses the y-axis; since the slope is the same for each option (m = 2), we focus on the y-intercepts. To find out the correct option, we can check if plugging in any given x-values leads to consistent y-values across the candidates. After verification, the equation corresponds to option C: \( y = 2x + 19 \). The line's slope indicates a rise of 2 units for every 1 unit it runs horizontally, giving it a steep yet consistent incline upward as you move across the x-axis. Keep an eye on your b-value; that's where your line will hit the y-axis!
