5. which ordered pair is a solution pf the equation y = -5x + 4 a. (2, 14) b. (5, -29) c. (3, -19) d. (5, -21) 7. -4 = g + 1 a. g = -4 b. g = 4 c. g = -5 d. g = -3 6.

1. Replace x with the given values and see if the equation equals the Y value:

y = -5x +4  

 -5(5)+4 - -25 +4 = -21

The answer is D.

2. -4 = g+1

Subtract 1 from each side:

-5 =g

The answer is C.

3.  The 2nd chart is correct, ( the top one on the picture with 2) because when Tony is 5 the line is on Y = 0, when the line is on 6 it is on Y=1, which keeps Tony at 5 years older.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
