(U6|L9 WU) Writing Linear Equations

Identify the equation that is correctly written in slope-intercept form.

•  $y=\frac{1}{2}x+6$  

•  $2x+6y=-15$  

•  $y-5=\frac{1}{3}\left(x+2\right)$  

•  $\frac{2}{3}x+y=5$

Identify the equation that is correctly written in standard form.

•  $y=\frac{1}{2}x+6$  

•  $2x+6y=-15$  

•  $y-5=\frac{1}{3}\left(x+2\right)$  

•  $\frac{2}{3}x+y=5$  

Identify the equation that is correctly written in point slope form.

•  $y=\frac{1}{2}x+6$  

•  $2x+6y=-15$  

•  $y-5=\frac{1}{3}\left(x+2\right)$  

•  $\frac{2}{3}x+y=5$  

What is wrong with this equation that was supposed to be written in slope intercept form?

 $y-6=\frac{2}{3}x+2$  

• the y should be isolated

• the x-term and y-term should be on the same side

• there should not be any fractions

What is wrong with this equation that was supposed to be written in standard form?

 $y=5x+2$  

• it is written correctly

• the x-term and y-term should be on the same side

• there should be fractions

What is wrong with this equation that was supposed to be written in standard form?

 $-5x+y=2$  

• it is written correctly

• the coefficient of the x-term should be positive

• the equation should be solved for y

What is wrong with this equation that was supposed to be written in standard form?

 $\frac{2}{5}x-y=-2$  

• it is written correctly

• the y-term should be positive

• there should not be any fractions

which is the correct first step to write the equation of the line that passes through the point  $\left(-2,\ 3\right)$   and has a slope of  $-\frac{5}{2}$  .

•  $y-3=-\frac{5}{2}\left(x-2\right)$  

•  $y-3=-\frac{5}{2}\left(x+2\right)$  

•  $y+3=-\frac{5}{2}\left(x-2\right)$  

•  $y+3=-\frac{5}{2}\left(x+2\right)$
