1. if x=4, what is the y value in the equation y = 3x +5?
a. 1/4
b. 4
c. 12
d. 17
2. in the following equation, what is the slope?

y = 5x + 3
a. 3
b. 5
c. 1/3
d. 1/5

3. in the following equation, what is the y-intercept?

y = 5x + 3
a. 3
b. 5
c. 1/3
d. 1/5

1.) D
y=3(4)+5
y=12+5
y=17
2.) A
y=mx+b
m is the slope which 5 is.
3.) A
the y-intercept takes in the place of b. which 3 is in the place of b.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
