Answer:
y=5x-6
Step-by-step explanation:
Comparing y=5x-6 with y=mx+c,the slope is 5 and y intercept is-6
Your answer would be either A...or D.
ANSWER

EXPLANATION
The given function is a piecewise defined function.

is the y-value that corresponds to

To determine that y-value, we need to trace from

to where it meets the graph.
We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.
From the graph, we can see that this x-value corresponds to a y-value of

This implies that, when

Therefore

See graph.
Answer:
Y=2x+0.5
Step-by-step explanation:
The gradient is 2/1=2x
The y-intercept looks to be around 0.5
