(random() > 0.5 ? -1 : 1) * (rand(5) + 1) (random() > 0.5 ? -1 : 1) * (rand(5) + 1) (random() > 0.5 ? -1 : 1) * (rand(3) + 1) 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 = \spacem\space \cdot x + \spaceb

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

y - y1 = \color{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.
