<span>7n + 4 - 5n <= 2(n+2) Let's simplify these expression first 2n + 4 <= 2(n + 2) 2(n +4) = 2n + 4 The LHS and RHS expressions are the same but the inequality says contrary Hence 2n + 4 is not less than but equal to 2(n + 2). 7+ 6a >= -4(2-a) - 2a -4(2-a) - 2a = -8 + 4a - 2a = -8 + 2a. It should be obvious that 7 +6a is greater than the RHS expression. Suppose a= 2 then we have 7 + 6(2) = 19 while -8 + 2(2) = - 8 + 4 = -4 So it follows that 7 + 6a >= -4(2-4) -2a 4x >= 8. The expression is always true so the equal to option is out.</span>

Write the equation in y=mx+b form please????
Solnce55 [7]

ANSWER

y =  - 2x - 5

EXPLANATION

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

m =  \frac{y_2-y_1}{x_2-x_1}

This implies that;

m =  \frac{5 - 1}{ - 5 -  - 3}

m =  \frac{4}{ - 2}  =  - 2

We can now find the equation using the formula;

y-y_1=m(x-x_1)

y   - 1 =  - 2(x  + 3)

Expand:

y =  - 2x -6 + 1

y =  - 2x - 5
