Write an equation for the line that is parallel to y = −2x and passes through the point (0, −7). y=2x-7

y=-2x+7

y=2x+7

y=-2x-7

y = -2x - 7

Step-by-step explanation:

Call

y = mx + b

the unknown line. We must determine m and b.

Since the line is parallel to y = −2x, our unknown line has the same slope m=-2

So

y = -2x + b

Since our line passes through (x,y) = (0, -7)

-7 = -2(0) + b ===> b = -7

Hence the line we are looking for is

y = -2x - 7

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
