The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
In this case, the slope is 5 and the y-intercept is -1. Therefore, the equation of the line is:
y = 5x - 1
This means that for any value of x, we can find the corresponding value of y on the line by plugging in x and solving for y. For example, if x = 2, then:
y = 5(2) - 1 = 9
So the point (2, 9) is on the line.
