Step-by-step explanation:
the right equation is :
y-y1=m(x-x1)
y+3=3(x+4)
y+3= 3x+12
y=3x+12-3
y=3x+9

Answer:
A
Step-by-step explanation:
We can see that Function A's y coordinate doubles every time. The function A = f(x) = 5(2)^x. It is an exponential growth function, and therefore y can never be 0. This means that A does not have an x-intercept.
Function B is a rational function. x cannot be 0, since that would result in an undefined number. This also means that B does not have an x-intercept.
