Best ResponseYou've already chosen the best response.1because for example if you have to unknowns and two equations, ex: y=x+5 and the other says x=y6.....then you would have to back substitue the y=x+5 into the value for y in the second equation.

Best ResponseYou've already chosen the best response.1because to find the x intercept you have to set the y intercept to 0

Best ResponseYou've already chosen the best response.0in finding the yintercept, assume that the value of x is zero, or vice versa. .

Best ResponseYou've already chosen the best response.0true or false? In order to solve a system of equation by substitution, you MUST always solve for y in one of the equations and hen backsubstitute The answer is false. And as far as y=x+5 you can solver for x. getting x=y5 You can solve for either x or y (assuming you have two equations with two unknowns x, and y. Choosing the one that is most convenient and then substitute the value found in the remaining unknown.

Best ResponseYou've already chosen the best response.0true or false? the xintercept of the line with equation 3x+2y=5 is (5/3,0) First put equation in the slope intercept form: You will get y=(3/2)x+5/2 The y intercept is 5/2
