What is the slope of the line containing the points (-6,4) and (2,1)

1 answer:

8 0

In order to find the slope, we need the formula (y2-y1)/(x2-x1). The x and y represent the point (x,y). (-6,4) is our first point. (2,1) is our second point. (1-4)/2-(-)6 > -3/2+6> -3/8

The slope is -3/8.

Answer:

1) $= 10 \frac{2}{5} = \frac{52}{5}$

2) $= \frac{252}{25} = 10 \frac{2}{25}$

Step-by-step explanation:

$6 \frac{4}{5} + 3 \frac{3}{5} \\ (6 + 3) + ( \frac{4}{5} + \frac{3}{5} ) \\ 9 + \frac{7}{5} = 9 + 1 \frac{2}{5} \\ 9 + 1 + \frac{2}{5} = 10 + \frac{2}{5}$

$\boxed{\green{= 10 \frac{2}{5} = \frac{52}{5}}}$

$2 \frac{4}{5} \times 9 \frac{2}{5} \\ \frac{14}{5} \times 9 \times \frac{2}{5 }$

$\boxed{\green{ = \frac{252}{25} = 10 \frac{2}{25}}}$

The graph shows a function.<br> Find the value of b and d.

True [87]

Answer:

<em>The required values are b=-6 and d=4</em>

Step-by-step explanation:

The graph corresponds to the function

$r(x) =x^2+bx^2+8x+d$

We are required to find the values of b and d.

They can be found by using two points that are clearly visible on the graph. For example, the points (0,4) and (2,0) belong to the function. Substituting their values in the function:

$4 =0^2+b*0^2+8*0+d$

Simplifying:

4 = d

d = 4

Now use the point (2,0):

$0 =2^2+b*2^2+8*2+d$

Since d=4, and calculating

$0 =4+4b+16+4$

Simplifying:

$4b = -24$

Dividing by 4:

$b = -24/4 = -6$

$b = -6$

The required values are b=-6 and d=4

Please help i'm struggling with this!It's urgent!

Answer:

12 should be 41

Step-by-step explanation:

12) the pattern is an increase by 5 each time. This would mean the 8th term is 40. However, it starts at 1, so you should add 1 to this answer, making it 41. This pattern is y=5x+1 if x is that number in the pattern and y is the answer.
