If (-3, y) lies on the graph of y = 3x, then y = a. 1/27 b. -1 c. -27

The correct value of y = -9.

Step-by-step explanation:

We know that there is a graph which represents the line and we are given a point (-3, y).

If this point (-3, y) lies on the graph, then we are to find the value of y.

For that, we will substitute the given coordinate of x in the equation of the line to find y:

Therefore, the correct value of y is -9.

y = -9

(-3 , - 9)

Step-by-step explanation:

Given that the equation of graph

y = 3x

and the co-ordinates are ( -3 , y )

where x = -3

So, put the value of x in the equation of graph above

y = 3(-3)

y = -9

The above answer is not in the options maybe the option is missing or something in question is missing. Let me know if question is not right so i can solve the right one for you.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

answer: correct
