Question

2. What is the x-intercept of the line that passes

through the point (-5,-9) and has a slope of 3?
A. (2,0)
B. (-2,0)
C. (6,0)
D. (-6,0)

Answer 1

Explanation:

hello :

an equation for the line is : y=ax+b when a is the slope

so : a= 3 y =3x+b

passes

through the point (-5,-9) x=-5 y= -9 means ; -9 =3(-5)+b so: b=6

conclusion : y=3x+6

Answer: B because y=0 3x+6 =0 3x =-6 x= -2
