over here. On the right is the slope intercept form of the equation of a line where Mr Slope N. B. Is the Y. Coordinate of the Y intercept. Our equation is not in slope intercept form, but it would be nice to get into that form so that we could find the sloping. Why intercept? So we're gonna isolate why? The first thing we could do is attract for X from both sides, and we have five y equals negative for X plus 25. Then we'll divide all the terms by five to get why by itself. And that gives us why equals negative 4/5 X plus five. Now we have slope intercept form and we can see the value of them is negative. 4/5. So that's our slope. And we can see the value of B is five. And that's the Y. Coordinate of the Y intercept. And the X coordinate of a Y intercept is always zero. So the Y intercept is the 0.5
