Question

I’m needin sum help.-.

Answer 1

The value of y when x is 3 in the equation "y = 4x + 4" is 16. This linear relationship reflects a consistent rate of change, with each unit increase in x corresponding to a 4-unit increase in y.

In the equation "y = 4x + 4," to find the value of y when x is 3, we substitute x with 3:

y = 4(3) + 4

y = 12 + 4

y = 16

Therefore, when x is 3, y is 16. This means the point on the graph is (3, 16). The equation represents a linear relationship where y depends on x with a constant rate of change of 4. For every 1-unit increase in x, y increases by 4 units due to the coefficient of x.

In summary, for the given equation "y = 4x + 4," when x is 3, y is 16. This relationship indicates a straight line with a slope of 4 and a y-intercept of 4.

The question probable may be;

Given the equation y = 4x + 4 find the value of y when x = 3.

Answer 2

y = 4x+4

give x a number that is on the X axis line to make it a little easier

so lets say x = 2

replace x in the equation with 2

y = 4(2) +4

so y = 8+4 =12

s0 put a dot where x is 4 and y is 12

do the same thing with another number then draw a straight line through both those points
