Answer:

a) Negative slope

m=-\frac{5}{8}

Step-by-step explanation:

The graph of the given line is shown in the attachment.

We can see from the grap that, the line is sloping backwards.

Therefore the line has a negative slope.

The given points are (-1,-3) and (7,-8).

We use the formula m=\frac{y_2-y_1}{x_2-x_1} to find the slope of this line.

\implies m=\frac{-8--3}{7--1}

\implies m=\frac{-8+3}{7+1}

\implies m=-\frac{5}{8}

We can confirm from the result of our calculation that the slope is actually negative.

-5(-x - 1) + 4x – 1= 49<br> solve for x
Anton [14]

Answer:

x=5

Step-by-step explanation:

-5(-x - 1) + 4x – 1= 49

Distribute

5x +5 +4x -1 = 49

Combine like terms

9x +4 = 49

Subtract 4 from each side

9x+4-4 = 49-4

9x = 45

Divide by 9

9x/9 =45/9

x = 5
