The coordinates below represent two linear equations. How many solutions does this system of equations have? Line 1 x y –3 5 0 4 Line 2 x y 0 4 6 2 A. 0 B. exactly 1 C. exactly 2 D. infinitely many
what do you think?
hint: find the slope of each line
yea could u graph it or do u know a website? @nikato
try this? http://go.hrw.com/math/midma/gradecontent/manipulatives/GraphCalc/graphCalc.html and go to plot points and type in your points
you could have actually solve for it. if you try to find the slope of each of them, you will find they both have a slope of -1/3. and because both their y-intercept is at 4, they are the same line
so B @nikato
no. infinitely many because they are the SAME line. all there points will be the same
0 is for parallel lines. 1 is for two intersecting lines. 2 is impossible. two lines cant intersect at two points. they wont even be lines
