Graphing linear equations
ella [17]

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:

ax + by = c

Therefore y=2x+4 in standard form is

2x - y =  - 4

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

y =  mx + c

where m is the slope and c is the y-intercept.

The given equation is

y =  -  \frac{1}{2} x  - 5

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.

What is the solution to this system of equations?<br> 3x + y = 17<br> x + 2y = 49
Anna007 [38]

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
