Which choice is the equation of a line that passes through point (7, 3) and is parallel to the line represented by this equation?y=2/7x-3
A. 7x + 3y = 2
B. y=2/7x+1
C. y=-7/2x-3
D. 2x + 7y = 1
**Weegy:**
A. 7x + 3y = 2 **User:** Which choice could be the equation of a line perpendicular to the line represented by this equation?
y = 5
A. y = 4x- 9
B. y=-1/5x
C. y = 5x
D. x = 5
**Weegy:** y = 5
This is an equation of a horizontal line that crosses the y-axis at (0, 5)
A perpendicular line would be a vertical line, whose equation looks like x = #, D is the only one that fits the case **User:** Which choice is the equation of a line that has a y-intercept of –3 and is perpendicular to the line represented by this equation?
y=2/3x+1 A.
B. y = 3x- 3

User: What does neutron absorption accomplish in a nuclear reactor?
A. It slows down the reaction.
B. It speeds up the reaction.
C. It increases the rate of heat absorption.
D. It recycles the fuel. **Weegy:** D. It recycles the fuel. **User:** What substances are used as moderators in a nuclear reactor?
A. carbon and water
B. liquid sodium and water

**User:** Which cells would be most sensitive to ionizing radiation?
A. cells that do not divide
B. cells that divide slowly
C. cells that divide rapidly
D. all cells **Weegy:** C. Cells that divide rapidly.
Ionizing radiation can cause mutations in nuclear and mitochondrial DNA. These mutations can build on each other in successive generations. [ This means that the more generations of cells the higher the concentration of these mutations and the larger the chance there will be an ill effect. ] **User:** What type of radiation is most likely to damage DNA?
A. ionizing
B. non-ionizing **Weegy:** Ionizing radiation is high-frequency radiation that has enough energy to remove an electron from (ionize) an atom or molecule. Ionizing radiation has enough energy to damage the DNA in cells, which in turn may lead to cancer. [ Gamma rays, x-rays, some high-energy UV rays, and some sub-atomic particles such as alpha particles and protons are forms of ionizing radiation. ] (More)
