Find the y intercept of -2,5 and 3,25

AlexFokin [52]

Answer:

Y-intercept = 13

Step-by-step explanation:

Since, given points are:

(-2,5) and (3,25)

Now, by slope intercept form:

y= mx + b

Here, m= slope and b= y-intercept

In order to find y-intercept, we must find slope firstly:

Since,

Slope= m= y2-y1 / x2-x1

m= 25 - 5 / 3 - (-2)

m= 20 / 5

m= 4

Put ‘m’ in slope intercept form:

y= 4x + b

Substitute either point into above equation:

25= 4(3) +b

25= 12 + b

25 - 12 = b

or b= 25 - 12

b= 13

Hence, y-intercept is 13.

Lynn measured the length of her front yard by counting her strides. The yard measured 18.5 feet long. Emily measured the same ya

Shalnov [3]

Answer:

8.11%

Step-by-step explanation:

We need to find the percentage error. We can follow the formula shown below:

$PE=\frac{New-Orig}{Orig}*100$

Where

PE is the Percentage Error

New is the newest measure (given as 20 feet)

Orig is the original, or first, measure (given as 18.5)

Substituting and finding the PE:

$PE=\frac{New-Orig}{Orig}*100\\PE=\frac{20-18.5}{18.5}*100\\PE=\frac{1.5}{18.5}*100\\PE=8.11$

Tagging the percentage , percent error is about 8.11%
