Question 76c55

Dec 6, 2016

Slope - intercept form.

Explanation:

•y=mx+blarr" slope-intercept form"

Refer to the question I did for you to see explanation.

•y=clarr"horizontal line"

where c is the value of the y-coordinate of a point that the line passes through.

• y-y_1=m(x-x_1)larr" point-slope form"

where m represents the slope and $\left({x}_{1} , {y}_{1}\right) \text{ a point on the line}$

• Ax+By+C=0larr" standard form"#

$\text{ for example}$ the equation y = - 2x + 3

would be written $2 x + y - 3 = 0 \text{ in standard form}$

$x = c \leftarrow \text{ vertical line}$

where c is the value of the x-coordinate of a point that the line passes through.
