Answer:
The answer is A
Step-by-step explanation:
I worked this out by substitution. I substituted 0 into x to find the y intercept.
y=2.50x+4.00
y=2.50(0)+4.00
y=0+4
y=4
We can graph the point (0,4). This means that the line must intercept (0,4) or the grapgh is inaccurate. The means that B and D are incorrect.
We can substitute 1 into the equation to see whether or not the equation has a positive or negative slope.
y=2.50x+4.00
y=2.50(1)+4.00
y=2.50+4
y=6.50
The increase from x=0 to x=1 is 6.50 (which is a positive number), so the line is positive (going from bottom left to top right of graph).
Therfore the answer is graph A.
