Sorry i’m not gonna graph it but with this info u easily can
the y intercept is -1
slope is 3/1
final equation is y=3x-1
Answer:
1/4
Step-by-step explanation:
Slope of a line can be found if given two points by using the formula
where
are points on the line.
However, I like to line up the points vertically and subtract then put 2nd difference over 1st difference.
Like this:
( 3 , 3 )
-( -1 , 2 )
---------------------
4 1
So the slope is 1/4.
Answer: 42/12 or 3.5
Step-by-step explanation:
5(6)/3(-4)= -30/12
-30/12 + 6 or -30/12 + 72/12 = 42/12 or 3.5
Answer:
Each slice of bread costs $0.06.
Step-by-step explanation:
To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.
Answer:
y = 2x-13
Step-by-step explanation:
The equation for a line is
y = mx+b where m is the slope and b is the y intercept
y = 2x+b
We know a point so we have a y and an x, so we can solve for b
-1 = 2(6) +b
-1 =12+b
Subtract 12 from each side
-1-12 = 12-12+b
-13 =b
Substitute this into y = 2x+b
y = 2x-13
