document.write( "Question 948924: 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? \n" ); document.write( "

y = 45 + 35x
\n" ); document.write( "Using commutative property of addition:
\n" ); document.write( "y=35x+45
\n" ); document.write( "This is slope intercept form:
\n" ); document.write( "y=mx+b, where b=value of y at the y-intercept.
\n" ); document.write( "By definition, the value of x at the y-intercept is 0, so the y-intercept is at the point (0,45)
\n" ); document.write( "
\n" );
