Which equations are in standard form? Check all that apply O y = 2x + 5
2x + 3y = -6
-4x + 3y = 12
Oy = {x-9
2x+3 = 6
O x-y=5
5x + 3y = }

What is the slope of a line that is perpendicular to y = 3x + 1

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
