First to answer will mark braineist. no work nessacary!

lets check 0,4  put in 0 for x

4*0+4   =4  good

4 * 2^0  =4  good

4*0+8 =8  no good

(0+2) ^2 =4   good

for the next point we only need to check 3 functions

(1,8)

4*1+4   =8  good

4 * 2^1  =*8 good

4x+8   don't care since it didn't work for (0,4)

(1+2) ^2=8   good

for the next point we need to check 3 functions

(2,12)

4*2+4   =12  good

4 * 2^2  =16   no good

4x+8   don't care since it didn't work for (0,4)

(2+2) ^2=16  no  good

Choice A

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

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

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
