Answer:
y = 2x - 19
Step-by-step explanation:
Slope-intercept form: y = mx + b
y = (x , y) = 1
m = slope = 2
x = (x , y) = 10
b = y-intercept
Plug in the corresponding numbers to the corresponding variables:
1 = 2(10) + b
First, simplify, and then isolate the variable, b. Note the equal sign, what you do to one side, you do to the other.
First, multiply 2 with 10:
1 = (2 * 10) + b
1 = 20 + b
Next, subtract 20 from both sides of the equation:
1 = b + 20
1 (-20) = b + 20 (-20)
1 - 20 = b
b = -19
Plug in 2 for m, and -19 for b.
y = 2x - 19 is your slope-intercept form.

We are looking for functions where f(-x) = f(x)
Let's test every function.
f(-x) = (-x)^4 - (-x)^2 = x^4 - x^2 = f(x)
The first function is even
f(-x) = (-x)^2 - 3(-x) + 2 = x^2 + 3x + 2 ≠ f(x)
The second function is not even.
f(-x) = √(-x-2) ≠ f(x)
The third function is not even
f(-x) = |-x| = |x| = f(x)
The last function is even.
Thus, the first and last choices contain even functions.
Have an awesome day! :)
