Final answer:
The equation y = mx + b represents a line, where m is the slope and b is the y-intercept. To identify points on the line, substitute x-values and solve for y.
Step-by-step explanation:
The equation y = mx + b represents a line, where m is the slope and b is the y-intercept. The slope determines the steepness of the line, while the y-intercept indicates where the line intersects the y-axis.
For example, if the slope is 2 and the y-intercept is 3, the equation becomes y = 2x + 3. To identify points on this line, you can substitute different x-values and solve for y.
When x = 0, you can find the y-intercept, which is the point where the line crosses the y-axis. In this case, the line intersects the y-axis at (0, 3). With different x-values, you can find other points on the line.
