The accurate statement which explains how to determine the slope (m) and y-intercept (b) of a line on a coordinate plane that goes through two points is:

C. To determine the y-intercept, move from the origin vertically to the graphed line. To find the slope, you will use two ordered pairs on the line and substitute into the equation $\mathbf{ m = (y_2 - y_1)/(x_2 - x_1) }$ .

Recall:

The y-intercept is the point at which the graphed line intercepts the y-axis (vertical axis). The y-intercept is the value of y here.

Slope (m) = $\mathbf{(y_2 - y_1)/(x_2 - x_1) }$

You can simply find the y-intercept on a coordinate plane like the one given in the image attached below.

To do this, from the point of origin (0), you have to move towards the graphed line, that's vertically upwards, to the point where the line crosses the vertical axis.

The y-intercept in the graph shown in the image = 2.

To find the slope, use two ordered pairs on the line, i.e., (0, 2) and (1, 5). (see attached image.)

Next is to let,

$(0, 2) = (x_1, y_1)\n\n(1, 5) = (x_2, y_2)$

Then, substitute the values into $\mathbf{ m = (y_2 - y_1)/(x_2 - x_1) }$

Thus:

$m = (5 - 2)/(1 - 0) = (3)/(1) \n\n\mathbf{m = 3}$

Therefore, the accurate statement which explains how to determine the slope (m) and y-intercept (b) of a line on a coordinate plane that goes through two points is:

8 9/25 as a percentage

Answers

Solve the proportion by multiplying the two numbers in opposite corners and dividing by the number in the corner opposite the '?'
Examples:

8 9/25 change the mixed number to a improper fraction by multipling the 25 by 8=200 then add 200+9 giving you 209/25 as the improper fraction.

Then you'll need to convert 209/25 = ?/100 divide 25 into 100 =4. then multiply 209*4= 836 so the answer is 836%

If the length and width of a rectangle A are each k times the length and width of rectangle B, which statement is true?A. The area of rectangle A is k^3 times the area of rectangle b

B. the area of rectangle A is k times the area of rectangle B

C. The area of rectangle A is 2k times the area of rectangle B.

D. The area of rectangle A is k^2 times the area of rectangle B.

Answers

Answer:

Step-by-step explanation:

"If the length and width of a rectangle A are each k times the length and width of rectangle B" means if rectangle B has L and W then rectangle A is k*L and k*W. So the area would be A = k*L*k*W = k^2 *L*W. D is correct.
