The solution is where the red line crosses the blue line, which on the X axis is between the 1 and the 2, so about 1.5.
Convert the fractions to decimal and see which one is close to 1.5:
13/8 = 1.625
25/16 = 1.5625
7/4 = 1.75
27/16 = 1.6875
The closest one to 1.5 is 25/16
Answer:
See attachment for graph
Step-by-step explanation:
Given

Required
The graph that shows the number of miles in x hours
We have:

Multiply both sides by x


So, the function is:

Slope-intercept form looks like this: y = mx + b. For your equation, simply add 3x on both sides: y = 3x + 19.
Rational number, because the Square root of 400 is 20, since 20 x itself is 400. Hope this helps!
