Document Summary
Relation between 2 variables that can be fit with line formula. Y = bx + a a = 0 *y-intercept. Y = f(x) or g= f(l: school a = point 1 (0,0) & point 2 (20,4) (cid:3051)(cid:3118) (cid:3051)(cid:3117)= (cid:2872) (cid:2868)(cid:2870)(cid:2868) (cid:2868)=0. 2 so g= bl = 0. 2l *flatter slope. = (cid:3052)(cid:3118) (cid:3052)(cid:3117) (cid:3051)(cid:3118) (cid:3051)(cid:3117)= (cid:2872) (cid:2868)8 (cid:2868)=0. (cid:887) so g= bl = 0. 5l *steeper slope. = (cid:3052)(cid:3118) (cid:3052)(cid:3117: school b = point 1 (0,0) & point 2 (8,4) G= bl + a: school a = point 1 (0,4) & point 2 (20,0) (cid:3051)(cid:3118) (cid:3051)(cid:3117)= (cid:2868) (cid:2872)(cid:2870)(cid:2868) (cid:2868)= 0. 2 so g= bl + a = 0. 2l + 4*flatter slope. = (cid:3052)(cid:3118) (cid:3052)(cid:3117) (cid:3051)(cid:3118) (cid:3051)(cid:3117)= (cid:2868) (cid:2872)(cid:2869)(cid:2868) (cid:2868)= 0. (cid:886) so g= bl + a = 0. 4l + 4 *steeper slope. = (cid:3052)(cid:3118) (cid:3052)(cid:3117: school b = point 1 (0,4) & point 2 (10,0) Y = bx + a a = 4 *y-intercept.
