 Hello and welcome to the session. In this session we discuss the following question which says, find the slope and y-intercept of the line 8x-4y is equal to 216. Let us first discuss the slope-intercept form of a line. It is given by y is equal to mx plus c where the coefficient of x that is m is the slope of the straight line and c that is the constant term in the equation is the y-intercept of straight line. This is the key idea that we use for this question. Let's proceed with the solution now. The given equation of line is 8x-4y is equal to 216. Let this be equation 1. We need to find the slope and the y-intercept of this straight line 1. Now we need to rewrite this equation 1 in the form y is equal to mx plus c so that we can easily find out the slope and the y-intercept of this line. Now 4 is a common factor in all the three terms of this equation. So taking 4 common we get 2x minus y is equal to 54. Now this equation can be further written as y is equal to 2x minus 54. Let this be equation 2. Now that we need to find the slope and y-intercept of this straight line. So now comparing equation 2 with the slope-intercept form of a line which is y is equal to mx plus c we get m as 2 and c as minus 54. Now that we know that m is the slope of the straight line and c is the y-intercept of the straight line. So we say that the slope of the line 8x minus 4y equal to 216 is 2 and the y-intercept of the line 8x minus 4y equal to 216 is minus 54. So this is the final answer for this question. This completes the session. Hope you have understood the solution of this question.
