How do you write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1,1)
harkovskaia [24]
First you have to put it into point-slope form before you can write it in slope-intercept form which is y-y1=m(x-x1)

Y-1=2(x-1)
Distribute the 2 to the x and -1
Y-1=2x-2
Move it all to one side
Y=2x-1

Use the slope formula to find the missing coordinate: R(0,_), S(-4,2) m=5
Delicious77 [7]

Answer

The missing value is 22

step-by-step explanation

The slope formula is

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

From the question,

m=5

x_2=-4

y_2=2

and

x_1=0

We substitute these values to get,

5=  \frac{2 - y_1}{ - 4- 0}

Simplify

5=  \frac{2 - y_1}{ - 4}

5 \times  - 4=2 - y_1

- 20=2 - y_1

- 20 - 2=- y_1

22= y_1

y_1 = 22

The missing value is 22

What is the range of the function y = 2sin X?
ruslelena [56]

Answer:

Range: [-2, 2] {y | -2 ≤ y ≤ 2}

Step-by-step explanation:

The given function is y = 2sinx

We have to find the range of the given function.

Since at y-axis sine function has the variance between -1 to 1 so range of y = sinx is [-1, 1]

and if the amplitude of sine function is 2 then sine function will vary from -2 to 2 which implies that range of y = 2 sinx will be [-2, 2]

So range of y = 2sinx is [-2, 2]
