A line has a slope of 1 and passes through the point (5,8). What is its equation in slope-intercept form? QUICKLY PLEASE+ BRAINIY AND 5 STAR

y = x + 3

Step-by-step explanation:

The slope intercept form is:

y = ax + b

where the a is the slope and b is the y intercept.

We know that the slope is 1:

y = 1x + b

and then the point:

8 = 1(5)+b

We can solve this:

8 = 5 + b

8 - 5 =  b

3 = b.

Then we can plug b back in for the slope intercept form:

y = x + 3

Hope that helps!

y = x+3

Step-by-step explanation:

If the slope is 1, thus y = 1(x) + b.

Substituting x = 5, y = 8 into the formula,

8 = 5 + b.

b = 3

Thus, the formula is y = x + 3.

answer: 7

step-by-step explanation: cause i checked it

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
