Answer:
3
Step-by-step explanation:
The notation "f(4)" means you put 4 where x is in the algebraic expression, then do the arithmetic.
f(4) = 2·4 -5
= 8 -5
= 3

Answer:
<h2>Check out the image.</h2>
Step-by-step explanation:
Let, the equation of the straight line is y = mx + c; where m is the slope of the equation and c is the constant.
The line has the slope 1.
Hence, the equation becomes y = x + c.
Since, the line passes through (-6, -2), -2 = -6 + c or, c = 4.
Hence, the equation of the straight line becomes y = x + 4.
Putting x = 0, we get, y = 4.
The line passes through (0, 4).
