Jeff has four grades from tests and iXL. Jeff's grades are 80, 86, 96, and 70. What expression could be used to find the grade Jeff needs on his next test if he wants an average of at least 85%? What grade does he need?

• 85 ≥ 1/5(80 + 86 + 96 + 70 + x)

  x ≥ 93

• 85 ≥ 1/4(80 + 86 + 96 + 70 + x)

  x ≥ 8

• 85 ≥ 1/5(80 + 86 + 96 + 70)x

  x ≥ 128

• 85 ≥ 1/4(80 + 86 + 96 + 70)x

  x ≥ 102

Solve for m  $y=mx+b$  

• $m=x+b-y$

• $m=y-b-x$

• $m=\frac{x-b}{y}$

• $m=\frac{y-b}{x}$
