PRACTICE GRAPHS (1) X 1.0 2.0 y -6±0.5 -1 ± 0.5 3.0 4±0.6 4.0 9±0.8 5.0 14±0.8 6.0 19±0.8 7.0 24±1.0 8.0 29± 1.0 9.0 34±1.5 Let's start with the straightforward data table. Plot a graph of y vs. x. Is it a straight line? Draw the best-fit line. Compute the slope for this line. Write the equation for y in terms of x using the straight-line equation y = mx + b, where m is the slope of the best-fit line, and b is the y-intercept. How is the b value measured directly from the graph?
