This is to be submitted at the beginning of the second class period. (use the conversion factors given in the discussion section as needed in these questions. these questions will be graded as right or wrong, based on your final answer. a correct numerical answer with the wrong significant figures will lose half-credit. your work must be shown to receive credit. units must be included. graphs will be graded for correct composition and labeling of the graph.) light travels at a speed of 3.0 times 10^10cm/sec. what is the speed of light in feet per hour? a recipe for onion soup to serve 30 people requires 4.2 pounds of onions. you are giving a dinner party for 18 people. how many pounds of onions do you need to make onion soup for the 18 guests? the density of gold is 19.3 g/cm^3. you inherit a gold bar that measures 7.0 inches by 3.0 inches by 2.0 inches. how many ounces does the bar weight?

The Correct option is ~ B

Let's find the slope (m) using points (2 , 1) and (0 , -3)

hence, slope = 2

now, by Observing the given graph we can infer that the given line cuts the y - axis at point (0 , -3), so value of y - intercept (c) = - 3

[ y - coordinate of a point when x - coordinate is equal to 0 is the value of y - intercept of a line ]

And, we know the general equation of line in slope - intercept form is ~

now, let's plug the value of slope (m) and y - intercept (c) in the general equation to find the equation of line in slope intercept form ~
