Write an equation in slope-intercept form for the line with slope 8 and $y$-intercept -7 .

Step 1 ：The slope-intercept form of a line is given by the equation \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept.

Step 2 ：In this case, we are given that the slope \(m\) is 8 and the y-intercept \(b\) is -7.

Step 3 ：We can substitute these values into the equation to get the equation of the line.

Step 4 ：Substituting the values we get \(y = 8x - 7\).

Step 5 ：Final Answer: The equation of the line in slope-intercept form is \(\boxed{y = 8x - 7}\).
