Equation of a straight line

Write the equation that describes each line in slope-intercept form.

slope is 3, (4,6) is on the line.

• $y=3x-5$

• $y=3x-6$

• $y=4x-3$

• $y=3x-4$

What is the equation in standard form of the line that passes through the point (6, -1) and is parallel to the line represented by 8x + 3y = 15.

• 8x+3y=-45

• 8x-3y=-51

• 8x+3y=45

• 8x-3y=51

Answer explanation

What happens to the slope of parallel lines?

Substitute the point (6, -1) into the answer choices and see which equals the answer.

Match the following

• standard form

• y=mx+b

• slope-intercept form

• x=d

• horizontal line

• vertical line

• y=b

• point-slope form

• Ax+By=C

What is the point-slope form of the given information:

*Hint: there are 2 right equations below
 $through:(2,-2),\ slope=-2$  

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

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

•  $y\ +\ 2\ =\ -2\left(x\ -2\right)$  

•  $y\ -\ 2\ =\ -2\left(x\ +2\right)$  

Given a line with a slope (m) of 3 that passes through the point (-6, -4), write the equation of the line in slope intercept form.

TRUE or FALSE

• True

• False

Which form is the equation in?

 $y=\frac{6}{5}x+4$  

• Slope-Intercept Form

• Standard Form

which line is perpendicular to the line

 $4x\ -\ 3y\ =\ 12$  

•  $3x\ -\ 4y\ =\ 12$  

•  $8x\ +\ 6y\ =\ -12$  

•  $12x\ -\ 14y\ =\ 2$  

•  $6x\ +\ 8y\ =\ -8$
