The linear equation graphed is given by:

y - 5 = 3(x - 1).

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In point-slope form, considering a point (x_0, y_0), the equation is:

y - y_0 = m(x - x_0)

The line goes through points (0,2) and (1,5), hence the slope is:

m = (5 - 2)/(1 - 0) = 3.

Since the line goes through point (1,5), the equation is:

y - 5 = 3(x - 1).

What's the slope of the line ? And explain please
tia_tia [17]
You take the difference between any two y and divide by the difference in the corresponding x. The number should be the same always for a straight line. That's your slope. A fancy way of writing it is dy/dx

so: (10-2)/(3-1) = 8/2 = 4 (using the first two points)
or: (26-2)/(7-1) = 24/6 = 4 (using the first and the last)

try it out for other combinations. The answer is 4 every time.

Sorry i have another question what is the inequality of 8x−8≤−72.
vova2212 [387]

That answer is x≤−8


Inequality:

8x−8≤−72


Step number  1:  You have to Add 8 to both sides.

8x−8+8≤−72+8

8x≤−64



Step number 2: You have to Divide both sides by 8.

8x /8  ≤  −64 / 8


Ur Answer:

x≤−8


Hope this helps :)

The slide at the playground has a height of 5 feet.
LenaWriter [7]

Answer:

Assuming the slide is straight - 12 feet

Step-by-step explanation:

Assuming the slide is straight - it creates a right triangle with long side 13 feet and one of the short sides of 5 feet. We need to find the other short side.

We know that:

x^2 + 5^2 = 13^2\\x^2 + 25 = 169\\x^2 = 144\\x = 12 \vee x = -12\textrm{; but -12 doesn't make sense}
