Answer:

B y=1/4x-2

Step-by-step explanation:

in y = mx + b

the b is the y intercept. this is where the line cuts through the y axis. you can see that it is going through the y axis at -2.

now look for your slope. I use rose over run. you can see that the line intersects at (4,-1)

"rise" is how far up or down to your next point."run" is how far left your right your next point is. in this case, the next point is 1 up and 4 to the right of a point. this translates to 1/4. this is a positive slope because your line goes upwards from left to right.

Find the equation of the linear function represented by the table below in slope-intercept form.

Y_Kistochka [10]

Answer:

y= 8x +7

Step-by-step explanation:

<u>slope-intercept form:</u>

y= mx +c, where m is the gradient (or slope) and c is the y-intercept.

Since it is a linear function, the gradient of any 2 points would be equal.

$gradient = \frac{y1 - y2}{x1 - x2}$

Thus, gradient of the line

$= \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8$

Subst. m=8 into the equation:

y= 8x +c

To find the value of c, substitute a pair of coordinates.

When x=0, y= 7,

7= 8(0) +c

c= 7

Thus, the equation of the linear function is y= 8x +7.

Which is the graph of the equation y-1=2/3(x-3)

lisov135 [29]

Step-by-step explanation:

Multiply 2/3 by (x-3) to get 2/3x -3.

Then subtract -1 on the y side to the right side compair like terms.

Answer:

By definition, a parallelogram is a figure that has opposite sides parallel or it has two pairs of sides that are parallel. Based on the given figure above, the additional facts that would guarantee that JKLM is a parallelogram are the following: JK= 8 and JM= 12 and JK= 8 and JK is parallel to LM. Hope this answer helps.
