problem on slope-intercept form

Topic:- slope-intercept form

The slope intercept form is probably the most frequently used way to express equation of a line. To be able to use slope intercept form, all that you need to be able to do is 1) find the slope of a line and 2) find the y-intercept of a line.

This math help gives you an example problem .

Question:-

Write the equation of a line perpendicular to y = 2/3 x-5 passing through(7,4)

Answer:-

   y = 2/3 x - 5 is of the form y = m x + c ,Which is slope-intercept form comaparing equation 1 and 2


we have slope m = 2/3

Two lines which are perpendicularto each other will satisfy the condition

 m1 * m2 = -1


slope of the line perpendicular to

y = 2/3 x - 5 is

   m2 = -3/2

equation of any line passing through (7,4) and having slope -3/2 is

  y-4 = -3/2 (x-7)

   2y+3x-29=0
