A line has a slope of 2 and passes through the point (3,8). What is its equation in slope-intercept form

y = 2x  + 2

Step-by-step explanation:

slope (m) = 2  ; (3 , 8)

Equation: y - y1 = m (x - x1)

                y - 8 = 2(x - 3)

                y - 8 = 2x - 2*3

                y - 8 = 2x - 6

                      y = 2x - 6 + 8

                      y = 2x  + 2

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
