The equation for a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
Given that the y-intercept is 9, we can substitute b = 9 into the equation:
y = mx + 9
To find the slope (m), we can use the x-intercept. The x-intercept is the point at which the line crosses the x-axis, so when y = 0. Substituting y = 0 into the equation:
0 = m(4) + 9
0 = 4m + 9
4m = -9
m = -9/4
Therefore, the equation for the line in slope-intercept form is:
y = -9/4x + 9
