Tayler claims that when a linear equation is written in general form, ax + by+ c = 0, the
x-intercept of the corresponding graph is always -(c/a)
a)show that tayler’s claim is true for the equation 3x+5y+ 45 = 0
b. explain why -(c/a) represents the x-intercept. (hint: what y-value can be substituted into ax +by+ c = 0 to determine the x-intercept? )
c. tayler’s claim is not true for horizontal lines. explain why.
d. suggest a similar rule for the y-intercept. check the rule using 3x+5y+ 45 = 0.
