Use the slope formula to find the slope of the line through the points (2,10) and (10,−8).
Salsk061 [2.6K]

The slope formula is the changes of two y-values over/to the changes of two x-values.

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

Substitute two given points in the formula to find the slope. The m-term represents the slope from y = mx+b.

\large{m =  \frac{10 - ( - 8)}{2 - 10} } \\  \large{m =  \frac{10 + 8}{ - 8} } \\  \large{ m =  \frac{18} { - 8} \longrightarrow  \frac{9}{ - 4} } \\  \large \boxed{m =  -  \frac{9}{4} }

Answer

  • The slope is -9/4.

Hope this helps and let me know if you have any doubts!

What values of b satisfy 4(3b + 2)2 = 64?
Vikentia [17]
Given the equation 4(3b + 2)² = 64, dividing both sides of the equation by 4, we have (3b + 2)² = 16 and getting the square root of both sides, (3b + 2) = 4 and (3b + 2) = -4 We can solve for b for each equation and have 3b = 2 | 3b = -6 b = 2/3 | b = -2 Therefore, the values of b are 2/3 and -2 and from the choices, the answer is <span>A: b = 2/3 and b = -2.</span>

One of the digits of a two digit number is three times the other digit. If you interchange the digits of this two digit number a
STatiana [176]

Answer:

62

Step-by-step explanation:

well, we start by expressing the number:

a b

we understand that using the above expression, the value of the number is 10a + b

using the information in the question,

a = 3b (1)

and,

11b + 11a = 88 (2) (derived using 10a + b form)

hence, when substituting (1) into (2):

11b + 33b = 88

44b = 88

b = 2 (3)

sub (3) into (1)

a = 6

hence, the number is 62
