Indicate the equation of the given line in standard form, writing the answer in the equation box below. The line containing the longer diagonal of a quadrilateral whose vertices are A(2, 2), B(–2, –2), C(1, –1), and D(6, 4).

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
