The slope-intercept form is y = m x + b y = m x + b , where m m is the slope and b b is the y-intercept. y = m x + b y = m x + b Find the values of m m and b b using the form y = m x + b y = m x + b . m = 0.75 m = 0.75 b = 0.25 b = 0.25 The slope of the line is the value of m m , and the y-intercept is the value of b b . Slope: 0.75 0.75 Y-Intercept: 0.25
Notice that 0.75 is 3/4 and 0.25 is 1/4, so the equation can be written into y=3/4 x+1/4. when x is o, y=1/4; when is 4, y=3 and 1/4. connect the two points, you have your graph.
