Bell Ringer Rewrite from standard to slope intercept form: 1. 2x + 4y = x + 8y = 32 Learning Target: I can graph the equation of a line from the intercepts.
Standard Form Ax + By = C X-Intercept—where the line crosses the x-axis Y-Intercept—where the line crosses the y-axis
X-intercept Means y=0 Step 1: “Cover” up y term Step 2: rewrite equation without y term Step 3: solve for x This is your x-intercept (x,0) Y-intercept Means x=0 Step 1: “Cover” up x term Step 2: rewrite equation without x term Step 3: solve for y This is your y-intercept (0,y)
X- and Y-Intercepts 3x + 4y = 24 X-Intercept Y-Intercept
X- and Y-Intercepts – 6y = 18 – x X-Intercept Y-Intercept
X- and Y-Intercepts y = 5x - 2 X-Intercept Y-Intercept
