{"Image DocumentName": "From Geometry: Any line can be described by an equation", "Image ImageDescription": "For any point on a line for X, there will be a corresponding Y. the equation for this is y = mx + b. m is the slope, b is the Y-intercept (when X = 0) Slope = change in Y per unit change in X. Y-intercept = where the line crosses the Y axis (when X = 0)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
