13. Which equation represents the line below?

Nonamiya [84]

Answer:

y = -2/3x + 3

Step-by-step explanation:

First, we need to calculate the slope of the line. We can do this by using the slope formula using two points:

(y₂ - y₁) / (x₂ - x₁)

If we take the points (-3,5) and (3,1), then: y₂ = 1; y₁ = 5; x₂ = 3; x₁ = -3

Next, we can substitute in values in the equation above to get (1 -5)/(3+3)

<em>** We got 3+3 because it was 3 - (-3), where two negatives equal a positive**</em>

Then, we get, -4/6, which simplifies to -2/3. Our slope is -2/3

After that, we need to find the y-intercept, which is where the line intercepts the y-axis. Here, that is at (0,3).

Therefore, if we put the above information into slope-intercept form:

y = mx + b --> m = -2/3; b = 3

y = -2/3x + 3

Though I don't think that answer choice is there...

Find a equation for the following pattern! Help!!!

tester [92]

Answer:

y = $\frac{1}{2}$ x

Step-by-step explanation:

The equation of a linear pattern has the form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (1, $\frac{1}{2}$ ) and (x₂, y₂ ) = (2, 1) ← 2 ordered pairs from the table

m = $\frac{1-\frac{1}{2} }{2-1}$ = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c use any ordered pair from the table and substitute into the partial equation.

Using (2, 1) , then

1 = 1 + c ⇒ c = 1 - 1 = 0

y = $\frac{1}{2}$ x + 0 ← equation for pattern or quite simply

y = $\frac{1}{2}$ x
