Reduce the Equation 5y+3 = 0 into intercept form and find its intercept on the axes.................

Reduce the Equation 5y+3 = 0 into intercept form and  find its intercept on the axes.................

Sol  : 



We have                        5y + 3 = 0

Or                                           5y = -3


Or                                       5y/3 = -3/3

Or                                    y/3/5   =  -1

Or                                    -y/3/5 = 1



Therefore      Intercepts on the axes are 0 and -3/5.............

Reduce the Equation 3x+2y-12=0 into intercept form and find its intercepts on the axes...........

Reduce the Equation 3x+2y-12=0 into intercept form and find its intercepts on the axes...........

Sol  :

here                                 3x+2y-12=0

Or                                          3x+2y = 12

Dividing by 12    we get,

                                               x/4 + y/6 = 1

Therefore                         Intercepts on the Axes are  4 and 6............

Reduce the Equation 6x+2y-5=0 into slope-intercept form and find its slope and intercept........

Reduce the Equation 6x+2y-5=0 into slope-intercept form and find its slope and intercept........

Sol   :

            Here Equation is
                                      6x+2y-5=0

Or                                           2y = -6x+5

Or                                             y = -6/2x+5/2

Or                                             y = -3x+5/2

Therefore                  Slope = -3      and Intercept = 5/2

Reduce the equation x+7y = 0 into slope intercept form and find its slope and the intercept.....

Reduce the equation x+7y = 0 into slope intercept form and find its slope and the intercept.....

Sol : 

             x + 7y = 0

Or        7y = -x

Or          y = -1/7x + 0

Therefore         Slope = -1/7      and     Intercept = 0

Find The angle between x-axis and the line joining the points A(3,-1) and (4,-2).

Q. No. 10 of Exercise 10.1 of class 11th

Find The angle between x-axis and the line joining the points A(3,-1) and (4,-2).


Sol :

Slope of the line joining the points A(3,-1) and (4,-2).

                          m = -2-(-1)/4-3
                             = -2+1/1
                             = -1/1
                             = -1
Or              tanx  = -1                   [ Since m=tanx]
                   tanx  = tan135
Therefore       x  = 135


Hence     The angle between x-axis and the line joining the points A(3,-1) and (4,-2) is 135
