Answer:
x-intercept: (-3,0)
y-intercept: (0,-3)
Step-by-step explanation:
Looking at the equation, we can see that it is already in standard form, or in a 
format. Whenever a line is put into standard form, the x-intercepts are represented by 
and the y-intercepts are represented by 
. So, let's calculate them by doing the following:
1) Find the x-intercept by using the formula. Substitute the number on the right side of the equation for 
and the coefficient for the x term for 
. So, in this case, 
and 
:
Therefore, the x-intercept is (-3,0).
2) Next, find the y-intercept by using the 
formula and substituting the right values. is still the number on the right side of the equation and 
is the coefficient of the y term. So, and 
.
Therefore, (0, -3) is the y-intercept.
7miles---------1hr
11.2miles------- x
cross multiply;
11.2 × 1 = 7 × x
x= 11.2÷7
x=1.6hr
If you want to express percentage as a decimal, you have to divide the number by 100:
79.2/100
The correct answer to this is:
0.792
