Unformatted text preview: your work!! =) Calculator Calculator check Upper Upper left y= button button (are any “Plot” dark?Unselect them) Write Write equation 2x—5 X button is to right of alpha key (—) is for negative numbers Use the operator — in right column Press Press graph: upper right Zoom: 6, zoom 5 to center on origin and make square Trace: 4 [enter] will show x=4, y=3 and flash Find Find equation from slope and point 2 − Sl Slope = 5 Point (—4, 1) Put m, x and y in Find b 3 − b= 5 Equation Equation of the line: put in m and b y = mx + b 2 1 = − (−4) + b 5 2 3 y =− x− 5 5 Slope Orientation of a line li change in y divided by change in x (0, -5), (-2, 0) Find from points y2 − y1 m= x2 − x1 Equation Equation from two points Fi Find slope y2 − y1 m= x2 − x1 Find the y-intercept using slope and one of the points Substitute m and b into slope-intercept equation y = mx + b Find Find equation from slope and point Sl Slope = m Point (x, y) right? Put m, x and y in Find b Equation of the line: put in m and b y = mx + b Parallel Parallel lines Have the same slope th But contain different points Write in slope-intercept form to find slope y = mx + b Find Find equation from slope...
