The initial value of the linear function represented by this graph is given by:
D. 7
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, the y-intercept is of 7, as the function goes through point (0,7), hence option d is correct.

To find the slope use the rate of change in y/the rate of change in x or you can use y2-y1/x2-x1

Answer:
26
Step-by-step explanation:
Given
4x - a ← substitute a = - 2, x = 6 into the expression
= 4(6) - (- 2) [ note - (- ) is equivalent to + ]
= 24 + 2
= 26
