What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 2 x + y - 1 = 0?

2x - y - 4 = 0
2x + y - 4 = 0
2x + y + 4 = 0

Determine whether the quadrilateral below is a parallelogram. justify/explain your answer (this means back it up! give specific information that supports your decision. writing just "yes" or "no" will result in no credit.)

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
