6x + 2y = 18
2y = -6x + 18
y = -3x + 9
Answer:
Step-by-step explanation:
58.6% of the total income is 17,000
let x represent the total income
58.6%(x) = 17,000...turn ur percent to a decimal
0.586x = 17,000
x = 17,000 / 0.586
x = 29010.238 rounds to 29,010.24 <== total yearly income
check...
58.6% of 29,010.24 = 17,000
0.586(29,010.24) = 17,000
17,000 = 17,000 (correct)
Answer:
7a+28b=21
Step-by-step explanation:
7×a=7a
7×-3= -21
7×+4b=+28b
so....
7a-21+28b=0
7a+28b=21
Hello!
So the equation that you want to use is
y = mx + b
Now you can plug in both the slope and your points to find b.
3 = -1/2(2) + b
3 = -1 + b
4 = b
So now that we've found b, we can use the original equation and only plug in the slope and b
y = -1/2x + 4
So to find the y-intercept, we need to plug in 0 for x
y = -1/2(0) + 4
y = 0 + 4
y = 4
Your y-intercept is (0,4)
Hope this helps!
