HELP PLEASE
y = −x + 2
y = 3x + 1
Which description best describes the solution to the system of equations?
Line y = −x + 2 intersects line y = 3x + 1.
Lines y = −x + 2 and y = 3x + 1 intersect the xaxis.
Lines y = −x + 2 and y = 3x + 1 intersect the yaxis.
Line y = −x + 2 intersects the origin.

Best ResponseYou've already chosen the best response.3dw:1440143370187:dw these are your x and y intercepts for your first equation connect the dots, also note that your equations are set up as y=mx+b format, which is equation of a line, where b is the y  intercept, and m is the slope. To solve for y  intercept (it's given +2) but you set x = 0 and solve for y To solve for x  intercept we set y = 0 and solve for x.

Best ResponseYou've already chosen the best response.1any 2 lines that don't have the same slope will intersect somewhere (if they DO have the same slope than they are parallel) any equation that has an intercept =0 will pass through the origin  otherwise it will NOT any line that has a slope = 0 will NOT intercept the x axis any lint at has slope "infinity" (i.e. has the form x = constant) will NOTintercept the Y axis. So you do not need to graph the lines  just look at the equations and the above facts and deduce the answer.

Best ResponseYou've already chosen the best response.3Good points, but I think you should still try to graph it out, if you're not sure and it's good practice!
