y = mx + b is the equation of a line;


m = slope , b = y-intercept


m = 4 : so we have : y = 4 x +b


We are give a set of points which it passes through, we can simply plug them in:


-2 = 4(3) + b (3 is the x and -2 is the y)


Then: -2 = 12 +b -14 = b


The final equation is : y = 4 x - 14

The answer is: y = 4 x - 14


I hope this helps have a fantastic day!!

y=mx+b is the equation of a line;

m=slope , b= y-intercept

m=4 ; so we have : y=4x+b

We are give a set of points which it passes through, we can simply plug them in:

-2 = 4(3)+b (3 is the x and -2 is the y)

We get -2 = 12 +b .... -14=b

our final equation is : y=4x-14

tamaranim1 [39]

Answer:

B)Only one graph intersects the y-axis above y=0

Step-by-step explanation:

Both functions are in y=mx+b. The y-intercept  is b.

f(x) has the y-intercept 3. It intersects above y=0.

g(x) has the y-intercept -4. It intersects below y=0.

This means B is correct.
