I do not understand how to transfer standard form into slope intercept form or point slope form or how to do it reverse.

Mathematics

Standard form: Ax + By = C
slope intercept form: y = mx + b
point slope form: y - y1 = m(x - x1)

lets use this equation as an example:
8x + 4y = 16    first subtract 8x
4y = -8x +16    then divide every number by 4
y = -2x + 4       this equation is now in slope intercept form

Answer:

a. Parallel

b. Not parallel

Step-by-step explanation:

Systems which have no solutions are parallel lines. These lines do not intersect and therefore have no solution. Remember, parallel lines have the same slope. Compare the slope in each equation when in y=mx+b format to see if they are parallel.

a. y= 2x + 3                                                  y-2x=-3 becomes y = 2x - 3

m = 2                                                            m= 2

The slopes are the same so these are parallel lines.

b. 3x + y = 2 becomes y= -3x + 2               y = 1/3 x + 1/2

m = -3                                                          m= 1/3

The slopes are different so this is not parallel.

Since -3 and 1/3 are the negative reciprocals of each other. These lines are actually perpendicular.

The table shows the outputs y for different inputs x:
Rasek [7]
Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.
(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.

Part B: All we have to do is plug in 11 for x in the function given to find the answer:
f(x)=5x-21\\f(x)=5(11)-21\\f(x)=55-21\\f(x)=34
In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.

Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:
f(x) = 5x-21\\99=5x-21\\99+21=5x-21+21\\120=5x\\120/5=5x/5\\24=x

which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3 ?
denis23 [38]

Answer:

y-2=\frac{1}{3}(x-3)

Step-by-step explanation:

we know that

The equation of the line into point slope-form is equal to

y-y1=m(x-x1)

in this problem we have

m=\frac{1}{3}

(x1,y1)=(3,2)

substitute the values in the formula

y-2=\frac{1}{3}(x-3)

Y=1/2x+2 which graph represents the function
Tanya [424]

Answer:

Graph number 1

Step-by-step explanation:

According to the equation the y-intercept is 2. The only graph with the y-intercept of (0,2) is the first graph. So, graph number 1 represents the function.
