Find the slope of the line that passes through the points (0,-11) and (8,-8).

Korolek [52]

To find the slope of a line, we can use the following formula:

$\displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }$

m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.

Let these be the following:

$\displaystyle \large{(x_1,y_1) = (0, - 11)} \\ \displaystyle \large{(x_2,y_2) = (8, - 8)}$

Substitute the points in formula:

$\displaystyle \large{m = \frac{ - 8 -( - 11)}{ 8 - 0} }$

Negative multiply negative always come out as positive.

$\displaystyle \large{m = \frac{ - 8 + 11}{ 8 - 0} } \\ \displaystyle \large{m = \frac{ 3}{ 8 } } \\$

Since m stands for slope, we can say that:

$\displaystyle \large \boxed{ \tt{slope = \frac{3}{8} }}$

Problem PageQuestion Tony estimated the height of his office building to be 45ft. The actual height of his office building is 41

Leona [35]

Answer:

The absolute error is 4 ft and percent error of Tony's estimate is 9.8%.

Step-by-step explanation:

Given:

Tony estimated the height of his office building to be 45ft. The actual height of his office building is 41ft.

Now, to find the absolute error and the percent error of Tony's estimate.

The height of his office building = 45ft.

The actual height of his office building = 41 ft.

So, to get the absolute error:

The height of his office building - the actual height of his office building

$45\ ft-41\ ft\\=4\ ft.$

The absolute error = 4 ft.

Now, to get the percent error of Tony's estimate:

$\frac{4}{41} \times 100$

$=0.0975\times 100$

$=9.75\%.$

Percent error of Tony's estimate rounding to nearest tenth = 9.8%.

Therefore, the absolute error is 4 ft and percent error of Tony's estimate is 9.8%.

Find the value of the variable if P is between J & K. JP = 3y+1 ; PK = 12y - 4 ; JK = 75

LuckyWell [14K]

JP + PK = JK
3y + 1 + 12y - 4 = 75
15y -3 = 75
15y = 75 +3
15y = 78
y = 78/15
y = 5.2

answer is a. 5.2
