# slope intercept form

#### anthonye

Hi;
I know the form y= mx + c, but is this the same y = m(x + constant) + c.

It's still a line, but with a different y intercept.
$$\displaystyle y = m(x - x_0) + b = mx + ( -mx_0 + b)$$

Is it still called slope intercept form even with the brackets.

Slope-intercept form is y= mx + c because m is the slope and c is the y-intercept.

y = m(x + constant) + c is not in slope-intercept form because although m is the slope, the y-intercept is not c.
