Answer:
To ensure uniformity on an exam
Or
To test whether you can distinguish between the two formats
Step-by-step explanation:
Standard form is when a straight line equation is rearranged in the form:

Therefore y=2x+4 in standard form is

The slope-intercept form is when a a straight line equation is written in the form:

where m is the slope and c is the y-intercept.
The given equation is

This is already in slope-intercept form:
The standard form and slope-intercept forms are just formats.
Your instructor may restrict you to leave your answer in one of these formats maybe for uniformity on a test.
You may also decide to rewrite an equation in slope-intercept form, so that you can easily identify the slope and y-intercept easily for graphing purpose.
Answer:
y=26, x=-3
Step-by-step explanation:
3x+y=17
3x+y-y=17-y
3x=17-y
Divide both sides by 3
Simplify
\frac{17-y}{3}+2y=49
\frac{17-y}{3}\cdot \:3+2y\cdot \:3=49\cdot \:3
17-y+6y=147
17+5y=147
17+5y-17=147-17
5y=130
\frac{5y}{5}=\frac{130}{5}
y=26
x=\frac{17-26}{3}
x=-3
