Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

Which rational number could be graphed between -4 and -5

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?
