Slope-intercept form formula: y=mx+b
our slope is undefined.
Answer:
Piyush walks faster than Laura
Step-by-step explanation:
we know that
The rate or speed is equal to the slope of the linear equation
<em>Laura</em>
y=3.5x
The slope is 
<em>Piyush</em>
Determine the slope of the line
we have the points
(0,0) and (4,18)
The line represent a direct variation (because passes through the origin)
so

For x=4 h, y=18 mi
substitute

Compare the slopes

therefore
Piyush walks faster than Laura
Answer:
P = 15a + 8b
Step-by-step explanation:
Profit is 15 on each of the 'a' units of A, and is 8 on each of the 'b' units of B. Hence the total profit (P) is ...
P = 15a +8b
If your objective is to maximize profit, the objective function is ...
P = 15a +8b
Well you could simplify the fraction(s) in question to their smallest form (where you can’t divide anymore without getting decimal answers) and see if they are equal to 1/4.
For example 2/8, you can divide both sides by 2 to simplify to 1/4, thus 2/8 is equivalent to 1/4.
Hope this helps!
