Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.
Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.
Which reduces to 8/1=8.
The slope of your equation is 8.
Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.
Plug the slope in:
y=8x+b.
Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).
-1=8(3)+b
-1=24+b
Subtract 24 from both sides.
-25=b
Now plug this into the equation!
y=8x-25 is your final equation.
I hope this helps :)
4/25.Example say if it was a tatol of 25pizzas slice you would have to give 4to a friend.Cause 4is a bigger #of 2 .Like 25is a bigger number then 15!
If by markup you mean discount then.....
1.5*0.07 = $0.105
That must be a very good pen ;D
Answer:
yards because it can't be squared if its a circle
Step-by-step explanation:
1st: 2x-3 2nd: 2x-1 3rd: 2x+1 4th: 2x+3
adding the above you get 8x=184
