I need help on question 1 of symbolic representation
monitta

Answer:

f(x) = 0x + 5

Step-by-step explanation:

Lets use the slope formula to determine the slope of this graph:

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1} } \\\\m=\frac{5-5 }{4-(-7)} \\\\m=0

SO we know the slope is zero.

If we know the slope is zero, then the y intercept must be at 5.

So the equation would be:

f(x) = 0x + 5
