The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
Given slope = -9, we can substitute this value into the equation: y = -9x + b.
To find the value of b, we can substitute the coordinates of the given point (1, 9) into the equation.
9 = -9(1) + b
9 = -9 + b
b = 9 + 9
b = 18
Therefore, the equation of the line in slope-intercept form is:
y = -9x + 18
Write the slope-intercept form of the equation of the line satisfying the given conditions.
Through (1,9); slope -9
