The point-slope equation of a line can be found by calculating the slope and substituting the values into the point-slope formula. For the given points (5,35) and (-6,-31), the equation becomes y - 35 = m(x - 5).
The point-slope equation of a line, also known as the slope-intercept form, is given by the formula y - y1 = m(x - x1), where m represents the slope of the line and (x1, y1) represents the coordinates of a point on the line.
To find the equation for the line passing through the points (5,35) and (-6,-31), we can use the following steps:
Using the point (5,35) as our reference, we can substitute x1 = 5 and y1 = 35 into the equation: y - 35 = m(x - 5).

If two marbles are drawn at random, the probability that they are both blue is 1/4
The formula for calculating the probability is given as:
Probability = Expected outcome/Total outcome
Since we are to find a probability of picking 2 blue balls
Pr(2 blue balls) = 6/12 * 6/12
Pr(2 blue balls) = 1/2 * 1/2
Pr(2 blue balls) = 1/4
Hence if two marbles are drawn at random, the probability that they are both blue is 1/4
