Answer:

slope = $\frac{7}{3}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Rearrange 7x - 3y = 21 into this form

Subtract 7x from both sides

- 3y = - 7x + 21 ( divide all terms by - 3 )

y = $\frac{7}{3}$ x - 7 ← in slope- intercept form

with slope m = $\frac{7}{3}$

trasher [3.6K]

Answer:

Step-by-step explanation:

Almost correct. I'd write this statement as follows:

"The area of a triangle is the product of the base and height of the triangle, divided by two."

or...

"The area of a triangle is half the product of the base and height."

DO,K = (5, 0) (10, 0) The scale factor is 1/2 2 5

Lapatulllka [165]

If the preimage point is (5,0) and the image point is (10,0)
then the scale factor is k = 2

Basically the coordinates of the old point have doubled (multiplied by 2)

x = 5 is the old x coordinate
x = 10 is the new x coordinate (5*2 = 10)

y = 0 is the old y coordinate
y = 0 is the new y coordinate (0*2 = 0, no change)
