Write an equation in slope intercept and form of the line through point(6,-1)with slope m=4

Mathematics
1 answer:
aniked [119]3 years ago
3 0

To solve this problem, we must first remember that slope-intercept form is y=mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept of the equation.

To begin, we can take this form and substitute in the slope for the variable m.

y = mx + b

y = 4x + b

Next, because we weren't given the y-intercept, we can find it by substituting the value of 6 for x and the value of -1 for y (these values came from the ordered pair that we were given in this problem).

-1 = 4(6) + b

After that, we can begin to simplify and solve for the variable b by computing the multiplication on the right side of the equation.

-1 = 24 + b

Next, we should subtract 24 from the right side of the equation in order to get the variable b alone.

-25 = b

Now, if we substitute in this value for the variable b in our equation with the slope, we get:

y = 4x - 25

Therefore, your answer is y = 4x - 25.

Hope this helps!

Jorge randomly selects a digit from 0 to 9. What is the probability that the digit he selects is a prime number?
zloy xaker [14]

Step-by-step explanation:

{0,1,2,3,4,5,6,7,8,9}--set of numbers from 0 to 9

{2,3,5,7}---set of prime numbers from 0 tp 9

there are 10 numbers in the first set and 4 numbers in the second set.

4/9 is the probability that the digit he selects is a prime number

Hope that helps :)

Cual de estos utiliza la propiedad distributiva para mostrar la forma expandida de la expresion: -4 . (-5 + 3)
mr Goodwill [35]

Respuesta:

8

Explicación paso a paso:

Si A, B y C son números enteros, según la propiedad distributiva;

A (B + C) = AB + AC

tenga en cuenta que A se distribuyó sobre B y C

Aplicando esto para expandir la expresión dada -4. (-5 + 3)

-4. (-5 + 3)

= -4 (-5) + -4 (3)

= 20 + (-12)

= 20 - 12

= 8

Por lo tanto, la respuesta requerida es 8
