Y = mx+b
m= 4
y= 4x+b
solve for b using (6,-1)
-1 = 4 (-1)+b
b=3
therefore equation is y=4x+3
same as (y+1)=4(x-6)
2/6 = 1/3
2/5 = 4/10
Hope this helps.
First one is 114
second one is 215.2
let me know if this doesn’t work :)
The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation <span>9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
</span>using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +-

/ 2(9)
