Write a linear equation from the graph.

This was super close to getting it right.

The slope formula is m=(y2-y1)/(x2-x1) with m being the slope and (x1, y1) and (x2, y2) being points.

The points you are working with are (0,4) and (5, 1). When I calculate the slope, it doesn’t matter which y coordinate I use first, as long as I use the x coordinate from the same point first in the denominator.

I’m now going to calculate the slope:
m = (1-4)/(5-0) = -3/5
(5,1) is a point, and because I used 1 first up top I used 5 first on the bottom.

The y-intercept is right, as when x = 0, y = 4.

The equation of the line is y = -3/5x + 4
You can double check this by creating your own graph.

The function y=h(x) is defined as follows:
Lunna [17]

Answer:

h(1) = 1

h(4) = 5

Step-by-step explanation:

Since 1 is in the interval 1 ≤ x ≤ 3, you must substitute 1 into the expression  x^{3}

So, h(1) = 1^{3} = 1

Since 4 is in the interval x > 3, and all values of x > 3 gives an output of 5, then h(4) = 5

If y varies directly with x, and y = 18 when x = 4, what is the constant of proportionality?
GREYUIT [131]
Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.

Dividing both sides by x for the given values, k becomes 18/4 = 4.5
