Find an equation of the line in slope intercept form. write the equation using function notation. through (5,5); parallel to f(x)=5x-5

The parallel line would have an equation of y = 5x - 20

In order to find this we need to start with the slope. The slope of a parallel line has the same slope. Since the coefficient of x (which is the slope) of the original equation is 5, we know the new slope is 5. Now we can take that and the point and put them both into slope intercept form to find the intercept.

y = mx + b

5 = 5(5) + b

5 = 25 + b

-20 = b

Now that we have the slope (5) and the intercept (-20), we can put them in for our final answer.

y = 5x -20

360/29

step-by-step explanation:

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
