Question: here is another question i have. the directions say, "write an equation in slope-intercept form that satisfies each condition." and here is a problem. "slope=-0.5, passes through (2,-3)". i know that the answer will have something like this= y=-0.5x because the slope is given so thats next to the "x". but whats with the rest? thank you so much whoever gets to answer.
