The slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept?

If the table of the function contains exactly two potential turning points, one with an input value of –1, which statement best describes all possible values of m? m ≥ –12 –12 < m < 4 m ≤ 4 m ≥ 4 or m ≤ –12

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

Can someone pls ! pls answer all. no explanation needed..
