Mathematics
1 answer:
allochka39001 [22]3 years ago

Answer:

y = 3x

Step-by-step explanation:

Let's select two points from the given graph.

(1,3) (3,9)

Now, let's use slope formula to find the slope.

m = y2-y1/x2-x1

= 9-3/3-1

= 6/2

= 3

Let's substitute/plug this value into the slope-intercept form.

y = 3x + b

We can see that the y-intercept is 0, from the graph.

b = 0

Therefore,

y = 3x

Answer:

a. (0, -2)

b. (1, -2)

c. (2, -2)

d. (3, -2)

e. (4, -2)

f. The y-value of the coordinate is always -2. The x-value of the coordinate is always what x is stated to equal.

Step-by-step explanation:

Since the linear equation y = -2 doesn't have a slope, it will be shown as a continuous horizontal line along, touching the y-axis at it's -2 unit.

Same could be said with the various x-equations, except they will be shown as continuous vertical lines.

f(-2) is x = -2

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    f(-2) = 3(-2)² - 7(-2)
  2. Exponents:                          f(-2) = 3(4) - 7(-2)
  3. Multiply:                               f(-2) = 12 + 14
