At Computer Central, the cost of renting a computer is $45 plus $35 per day. The total cost can be represented by the equation y = 45 + 35x, where x is the number of days for which the computer has been rented and y is the total cost of renting the computer. What is the y-intercept of this equation? Record your answer on the grid.

Y-intercept form is y=mx + b, if we put the equation into this form we get y=35x + 45
 b is the y-intercept, which is 45 in this equation.  The point where the equation crosses the y-axis (y-intercept) is (0,45).
