Which equation could represent the relationship shown in the scatter plot? 1.y=12x+7 2.y=3x 3.y=−x+8 4.y=52x−1 Scatter plot with x axis labeled variable x and y axis labeled variable y. Points go from lower left to upper right.

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
