Answer: The slope of the line is 1.5 and the y-intercept is -2.
Step-by-step explanation: We are given that the equation of a straight line is as follows :

We are to find the slope and y-intercept of the given line.
We know that
the slope-intercept form of the equation of a straight line is given by
where m is the slope and c is the y-intercept of the line.
From equation (i), we have

Comparing the above equation with the slope-intercept form, we get
slope, m = 1.5 and y-intercept, c = -2.
Thus, the slope of the line is 1.5 and the y-intercept is -2.
