Compose the result function for y=2x - 7 by replacing function designators with the actual function y= 2x - 7
spin [16.1K]3 years ago

Y = 2x - 7...the slope here is 2. A parallel line will have the same slope and a perpendicular line will have a negative reciprocal slope.

parallel line....
In y = mx + b form, the m is ur slope and the b is ur y int. A parallel line will have the same slope but will have a different y int. So one  parallel line could be : y = 2x + 7.....or y = 2x - 4....that last number can be anything else but -7.

perpendicular...
perpendicular lines have negative reciprocal slopes. To find the negative reciprocal of a number, just flip the slope and change the sign. So the negative reciprocal of 2 (or 2/1) is - 1/2....see how I flipped the slope and changed the sign. So our perpendicular line will have a slope of -1/2. So one perpendicular line could be : y = -1/2x + 5...or y = -1/2x - 2.....doesn't really matter what the last number is, just as long as ur slope is -1/2.

(1) 2 of one step equations

x - 23 = 8
x - 23 + 23 = 8 + 23
x = 31

n + 2 = 9
n + 2 - 2 = 9 - 2
n = 7

(2) 2 equations with fractions

3/4 (x + 3) = 9
4 [ 3/4 (x + 3) ] = 4[9]
3 (x + 3) = 36
3x + 9 - 9 = 36 - 9
3x/3 = 27/3

1/3 x 3/4
cross multiply
so 3/12 and simplify which makes it
1/4

(3) distributive property

3(2 + 4) = (3 • 2) + (3 • 4)
3(6) = 6 + 12
18 = 18
