Final answer:
The equation of a straight line is represented by y = mx + b. In this equation, m represents the slope and b represents the y-intercept. The given example has a slope of 5 and a y-intercept of 7.
Step-by-step explanation:
The equation of a straight line is represented by y = mx + b. In this equation, m represents the slope and b represents the y-intercept. The slope is a measure of how steep the line is, and the y-intercept is the point where the line crosses the y-axis.
In the given example, the equation y-7=5x has a slope of 5 and the y-intercept is 7. This means that the line has a steepness of 5 and it intersects the y-axis at the point (0, 7).
