7 0

Answer:

6x-11

Step-by-step explanation:

m=y2-y1

x2-x1

-17--5 = -12

3-1. -2

The two negatives cancel ❌

m=12

Divide by 2

m=6

y=mx+b

-5= 6 (1) + b

-5= 6 + b

Subtract (6) from both sides

b= -11

The equation for the line is 6x -11

Answer:

x = -1, -5

Step-by-step explanation:

${(x + 3)}^{2} = 4 \\ = > {x}^{2} + 2 \times x \times 3 + {3}^{2} = 4 \\ = > {x}^{2} + 6x + 9 = 4 \\ = > {x}^{2} + 6x = 4 - 9 \\ = > {x}^{2} + 6x = - 5 \\ = > {x}^{2} + 6x + 5 = 0 \\ = > {x}^{2} + 5x + x + 5 = 0 \\ = > x(x + 5) + 1(x + 5) = 0 \\ = > (x + 1)(x + 5) \\ = > x = - 1 \: \: or \: \: - 5$
