The equation, in point-slope form is (y - 45) = 5(x - 9) option first is correct.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
A manager measured the number of goods, y, that his company produced in x hours.
The slope:
m = 5
From the problem:
The point (9, 45) will satisfy the line.
(y - 45) = 5(x - 9)
Thus, the equation, in point-slope form is (y - 45) = 5(x - 9) option first is correct.
