Answer:

y = (2/5)x + 3/5

Step-by-step explanation:

Points to remember

Equation of the line passing through the poits (x1, y1) and (x2, y2) and slope m is given by

(y - y1)/(x - x1) = m where slope m = (y2 - y1)/(x2 - x1)

To find the slope of line 

Here (x1, y1) = (-4, -1) and (x2, y2) = (6, 3)

Slope = (y2 - y1)/(x2 - x1)

= (3 - -1)/(6 - -4)

= 4/10 = 2/5

To find the equation 

(y - y1)/(x - x1) = m

(y - -1)/(x - -4) = 2/5

(y + 1)/(x + 4) = 2/5

5(y + 1) = 2(x + 4)

5y + 5 = 2x + 8

5y = 2x + 3

y = (2/5)x + 3/5

Answer:

y=2/5x+3/5

Step-by-step explanation:

Use the slope formula to get the slope:

m=4/10

m=2/5

The y intercept is 3/5

The equation is y=2/5x+3/5

Given:

32 and 28 are the two numbers.

To find:

(a) The GCF of 32 and 28.

(b) Using the GCF, find the factor of (32-28).

Solution:

(a)

The factor forms of the given numbers are:

$32=2\times 2\times 2\times 2\times 2$

$28=2\times 2\times 7$

It is clear that, 2 and 2 are the common factors in both.

$GCF(32,28)=2\times 2$

$GCF(32,28)=4$

Hence, the GCF of 32 and 28 is 4.

(b)

Using the GCF we need to find the factor of (32-28).

$32-28=4\times 8-4\times 7$

Taking out the GCF, we get

$32-28=4\times (8-7)$

Hence, $32-28=4\times (8-7)$ .

Chris ran 40 yards in 4.24 seconds what is the rate of speed

Sonja [21]

Distance divided by time is speed. To find the rate of speed, divide 40 yards by 4.24 seconds which is approximately 9.43 yards per second. 9.43 yards per second is the rate of speed.
