A straight line goes through the point (7, 5) with a slope of 2. What is the equation of the line?

Th equation of a line is denoted as y = mx + c, with m as the slope and c as the y intercept. We already know that the slope is 2. Since the line passes through the point (7, 5) we can input these values for x and y into the equation.Thus, 5 = 2(7) + c.Solving for c then gives c = 5 - 2(7) = 5 - 14 = -9.Now that we have the y intercept, we can write the full equation of the line.y = 2x - 9
