Identify the domain and range of the relation {(−1, 1), (0, 2), (3, −2), (5, 2)}. A. domain: {−2, 1, 2}; range: {−1, 0, 3, 5} B. domain: {−1, 0, 3, 5}; range: {−2, 1, 2} C. domain: all real numbers; range: all real numbers D. domain: {−1, 1, 0, 2}; range: {3, −2, 5, 2}

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
