The slope is already given in the question, so we only ned to solve for the y-intercept using y = mx + b.
4 = 3(1) + b
4 = 3 + b
4 - 3 = 3 + b - 3
1 = b
Now, write the equation in slope-intercept form.
y = 3x + 1

Answer:
$16.80
Step-by-step explanation:
20 % of 20 is 4 and you would take the 4 off for a discount. 5% of 16 is 0.8 and you would add it since it's an additional tax.
2.0x5 would eqaul 5 plus the samll 2 minus 15 then u would get b
Answer:27
Step-by-step explanation:108 divided by 4 is 27
Answer:
C 12/48
Step-by-step explanation:
Original fraction:
x/y
The ratio of the numerator to the denominator is 1:4, so
x/y = 1/4
Cross multiply:
y = 4x
If three is added to the numerator and subtracted from the denominator, the new fraction reduces to one-third.
(x + 3)/(y - 3) = 1/3
Cross multiply:
3(x + 3) = 1(y - 3)
3x + 9 = y - 3
Above, we have y = 4x, so substitute 4x for y in the equation just above and solve for x.
3x + 9 = 4x - 3
12 = x
x = 12
y = 4(12) = 48
The original fraction is x/y = 12/48
