Answer:
The equation is 
Step-by-step explanation:
Let the time for which i bike is = x hours
Let the distance traveled in x hours = y miles
Ratio of distance and time will be = x : y
I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112
then the ratio of distance and time will be same in both the cases
So equation will be
Hence, equation representing the proportional relationship will be
The slope intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0). We are given that the slope is 4/5 and the point (0,1) so we know m=4/5 and b=1 so:
y=4x/5+1 now to rearrange into standard form ax+by=c
y=(4x+5)/5
5y=4x+5
5y-4x=5
So the answer is D.
However, by convention, in standard form, the equation is usually expressed with a positive coefficient for x.
5y-4x=5 SHOULD be expresses so the x has a positive coefficient, divide both sides by -1 and you have the technically correct form:
4x-5y=-5
Apparently whomever/whatever posed this question to you was unaware of this convention :P

Answer:
The Answer would be Z.
Step-by-step explanation:
I took 30 from the image with a scale factor of 3 and divided it by 3. Now im at a scale factor of 1 and then i multiplied it by 2 to reach the scale factor of 2. I did this for every single side by dividing them by 3 and then mulitpiing them by 2. Therefore, i got the answer that <u>model Z is your answer.</u>

30/3 = 10 24/3 = 8 18/3 = 6
10 x 2 = 20 8 x 2 = 16 6 x 2 = 12

Answer:
option 4
Step-by-step explanation:
Take any point on the graph different from (0, 0). For example, (2, 10) and se which function verifies:
y = 10x ----> 10 = 10*2 = 20 so NOT
y = 1/5x ----> 10 = (1/5)*2 = 2/5 so NOT
y = 2x ----> 10 = 2*2 = 4 ----> so NOT
y = 5x ----> 10 = 2*5 = 10 -----> YES!!
So, f(x) = 5x verifies and matches the graph
