What is an equation in point slope form of the line that passes through -3, -1 and has a slope of 2
Masja [62]

Answer:

y+1=2(x+3)

Step-by-step explanation:

we know that

The equation of a line in point slope form is equal to

y-y1=m(x-x1)

we have

m=2\\(x1,y1)=(-3,-1)

substitute

y+1=2(x+3)

Write the equation of a line in Slope Intercept Form that passes through (−2,5) and (3,15).
Inessa [10]

Answer:

\displaystyle y = 2x + 9

Step-by-step explanation:

First, find the <em>rate of change</em> [<em>slope</em>]:

\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-5 + 15}{2 + 3} = \frac{10}{5} = 2

Then, plug the coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because since you get it done much faster that way. It does not matter which ordered pair you choose:

15 = 2[3] + b

6

\displaystyle 9 = b \\ \\ y = 2x + 9

_______________________________________________

5 = 2[−2] + b

−4

\displaystyle 9 = b \\ \\ y = 2x + 9

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

I am joyous to assist you anytime.

Which is the graph of the rose curve
Vinil7 [7]

<h2>(<em>LETTER A</em>)</h2>

<h3>How do you identify a rose curve?</h3>

Rose curve equations have two forms: r = a cos(nθ) and r = a sin(nθ) where a ≠ 0 and n is a positive integer. Petals have length determined by a. If n is odd, the number of petals is n. However, if n is even, the number of petals is 2n.

Question 13<br> Help please
Nitella [24]

9514 1404 393

Answer:

  f(x) = 11x -15

Step-by-step explanation:

Often, we let x represent the input to a function. When that is multiplied by 11, the result is represented by 11x. If 15 is subtracted from that, then the expression becomes ...

  11x -15

If this value is the output of function f, we write this as ...

  f(x) = 11x -15
