Question

If the slope of a line is ½ and the y-intercept is 3, what is the x-intercept of the same line?
a. 6
b. 3/2
c. 0
d. -2/3
e. -6

Answer 1

the equation of the line is y=1/2x+3. 
To find the x intercept, we calculate the x value when y=0, because this occurs at the x-intercept.
so, 0=1/2x+3
0=x+6
-6=x
answer: E
