Select the correct answer. Consider the formula for the slope between two coordinate points, m, shown below. M=y2-y1
X2-x1

The sum of the product of 4 and x and the product of 7 and y is 61. the sum of the product of 12 and x and the product of 21 and y is 61. what are the values of x and y?

What is the equation of the graph below? y=sec(x)-4

Me. i can't figure out this question. give an explanation too. .
