Identify the x-coordinate for the solution to the system of equations. Solve the system using substitution. x=4y+5

7x - 2y = 35

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

Find the coordinates of point x that lies along the directed line segment from y(-8, 8) to t(-15, -13) and partitions the segment in the ratio of 5: 2.
