Solved by pluggable solver: Converting Linear Equations in Standard form to Slope-Intercept Form (and vice versa)

Convert from standard form (Ax+By = C) to slope-intercept form (y = mx+b)

$\"-9x-8y=-64\"$ Start with the given equation

$\"-9x-8y%2B9x=-64%2B9x\"$ Add 9x to both sides

$\"-8y=9x-64\"$ Simplify

$\"%28-8y%29%2F%28-8%29=%289x-64%29%2F%28-8%29\"$ Divide both sides by -8 to isolate y

$\"y+=+%289x%29%2F%28-8%29%2B%28-64%29%2F%28-8%29\"$ Break up the fraction on the right hand side

$\"y+=+%28-9%2F8%29x%2B8\"$ Reduce and simplify

The original equation $\"-9x-8y=-64\"$ (standard form) is equivalent to $\"y+=+%28-9%2F8%29x%2B8\"$ (slope-intercept form)

The equation $\"y+=+%28-9%2F8%29x%2B8\"$ is in the form $\"y=mx%2Bb\"$ where $\"m=-9%2F8\"$ is the slope and $\"b=8\"$ is the y intercept.

Solved by pluggable solver: Converting Linear Equations in Standard form to Slope-Intercept Form (and vice versa)

Convert from standard form (Ax+By = C) to slope-intercept form (y = mx+b)

$\"7x%2B2y=-11\"$ Start with the given equation

$\"7x%2B2y-7x=-11-7x\"$ Subtract 7x from both sides

$\"2y=-7x-11\"$ Simplify

$\"%282y%29%2F%282%29=%28-7x-11%29%2F%282%29\"$ Divide both sides by 2 to isolate y

$\"y+=+%28-7x%29%2F%282%29%2B%28-11%29%2F%282%29\"$ Break up the fraction on the right hand side

$\"y+=+%28-7%2F2%29x-11%2F2\"$ Reduce and simplify

The original equation $\"7x%2B2y=-11\"$ (standard form) is equivalent to $\"y+=+%28-7%2F2%29x-11%2F2\"$ (slope-intercept form)

The equation $\"y+=+%28-7%2F2%29x-11%2F2\"$ is in the form $\"y=mx%2Bb\"$ where $\"m=-7%2F2\"$ is the slope and $\"b=-11%2F2\"$ is the y intercept.
