Is y = -70x + 300 a negative or positive slope

Slope-intercept form:   y = mx + b  [m is the slope, b is the y-intercept or the y value when x = 0 -->  (0, y)]

y = -70x + 300

m is -70, so it is a negative slope

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
