How to find slope intercept form with one point and the slope?
andre [41]
Slope intercept form is y = mx + b...ur slope will be in the m position and ur y int will be in the b position

examples : slope = 2 , (1,3)....x = 1 and y = 3

y = mx + b
slope(m) = 2
(1,3)...x = 1 and y = 3
now we sub and find b, the y int
3 = 2(1) + b
3 = 2 + b
3 - 2 = b
1 = b

so in slope intercept form, ur equation is : y = 2x + 1
================
another example : slope = 3 , (-2,-4)

y = mx + b
slope(m) = 3
(-2,-4)...x = -2 and y = -4
now sub and find b, the y int
-4 = 3(-2) + b
-4 = - 6 + b
-4 + 6 = b
2 = b
so ur equation is : y = 3x + 2

valentina_108 [34]

1. 5/6 = 10/12

  3/4 = 6/8

2. 2/9 = 4/18

   4/12 = 1/3

3. 6/7 = 12/14

   1/2 = 2/4

4. 5/9 = 10/18

   3/18 = 1/6

5. 1/6 = 2/12

   1/9 = 2/18

6. 3/8 = 6/12

Evaluating a piece-wise function. 10 pts
kozerog [31]
1. Since -4 doesn’t equal -2, we will use the first function. All you have to do is plug in -4 to x, and you should get

-3

2. -2=-2, so we will use the second function to get the answer of

3

3. Once again we will be using the first function, so just plug 5 into the answer to get

-7.5

Hope this helped :)
