randRangeNonZero(-5, 5) randRangeNonZero(-5, 5) randRangeNonZero(-3, 3) m*x1+b m*x1

Convert the following equation from point slope to slope intercept form.

In other words, if the equation is rewritten to look like `y = mx + b`, what are the values of `m` and `b`?

`y - y1 = m(x - x1)`

`y = \space` m`\space \cdot x + \space` b

Distribute the `m` in the `m(x - x1)` term on the right.

`y - y1 = \blue{expr([ "*", m, "x" ]) - var1}`

Isolate the y term on the left by subtracting `-y1` from both sides. adding `y1` to both sides.

`y = expr([ "*", m, "x" ]) - var1 + y1`

Combine the constant terms on the right.

`y = expr([ "*", m, "x" ]) + b`

The equation is now in slope-intercept form, with a slope of `m` and a y-intercept of `b`.
