Answer:

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is equal to 0)
<u>1) Determine the slope (m)</u>
where two points that the line passes through are
and 
We're given the point (2,10) and the y-intercept of 4. Recall that the y-intercept occurs when x is equal to 0. This means that the y-intercept occurs at (0,4), giving us our second point.
Plug these points into the equation

Therefore, the slope of the line is 3. Plug this into 

<u>2) Determine the y-intercept (b)</u>
The y-intercept is given; it is 4. Plug this back into 

I hope this helps!
Answer:
The number of hours that she work for the fast food is 11
The number of hours that she mowed is 5
Step-by-step explanation:
let x= hours spent mowing
y= hours spent at the food joint.
we can now form an equations from the figures given.
x+y=16...*
10.5x+4.25y=136.75...**
solving the two equations simultaneously using the substitution method or the eliminating method,
x=11 hours
y=5 hours
