The linear function which represents the line is y = - 3x + 14.
What is Point slope form?
Point slope form is used to represent a straight line using its slope and a point on the line. It means that the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point-slope form.
Main body:
y - y1 = m (x - x1)
where, (x, y) is a random point on the line and m is the slope of the line.
The given point-slope equation is
y + 1 = - 3 (x - 5)
By further calculation
y + 1 = -3x + 15
y = -3x + 15 - 1
y = -3x + 14
Therefore, the linear function which represents the line is y = - 3x + 14.
