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 = \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.
