Point-slope of line's equation (-3,-7),(-8-11)

1 answer:

3 0

Steps:
1. Find the slope by using the slope formula
Y2-Y1
---------
X2-X1

-11 + 7
----------
-8 + 3
2.
-11 + 7= -4
-8 + 3= -5
3. Your slope is 4/5 (because you have to turn two negatives into a positive)
4. Now you do the point-slope formula
Y-Y1= m(x-x1)
Y +7=4/5 (x +3)

The graph of y=f(X) is shown below. Graph y=1/2f(x)

lubasha [3.4K]

Answer:

The grap is a partial line , showing to be negative. The y-int is -3 and the slope is -1/2

Top answer · 0 votes

So then the linear function is y = f(x) = (-1/2)X - 3 y = g(x) = 1/2 * f(x) = (-1/4)x - 3/2 y-intercept is (-1/4)(0) - 3/2 = 0 - 3/2 = -3/2 ... More

hello, John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4

oksian1 [2.3K]

Answer:John's error is that he applied the transformation rule to the image instead to the pre-image.The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5). This results to (4, 5) + (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image.

Find Z for the following proportion

krek1111 [17]

This is the simplest proportion i have seen.
This is how we do it:
$\frac{z}{7}$ = $\frac{1}{7}$
The answer surprisingly is obvious, z = 1
But we can still do cross multiplication

7z = 7
Divide by 7 to isolate z

$\frac{7z}{7} = \frac{7}{7}$
7 and 7 cancels out
z = 1
