Question

Tayler claims that when a linear equation is written in general form, Ax + By+ C = 0, the

Answer 1

     Ax + By + C = 0
A. 3x + 5y + 45 = 0
    3x + 5(0) + 45 = 0
    3x = -45
    x = -45/3......x int.....-C/A
    x = -15

B. To find the x intercept, u must sub in 0 for y and solve for x

C. This is not true for a horizontal line because u can't sub in 0 for x because a horizontal line never crosses the x axis and therefore, does not have an x axis.

D. y int is -C/B....u find this by subbing in 0 for x and solving for y
   3x + 5y + 45 = 0
   3(0) + 5y + 45 = 0
   5y = -45
   y = -45/5......y int = -C/B
   y = -9
