Use a graphing calculator to solve the system of linear equations. 2.1x+4.2y=14.7 −5.7x−1.9y=−11.4
1 answer:
I used my calculator and got x=1 y=3
solve for y to put them in your calculator
2.1x+4.2y=14.7
y = (14.7 -2.1x)/4.2
−5.7x−1.9y=−11.4
y=(-11.4 +5.7x)/(-1.9)
then using the ploting tool I plotted them and found where they intersected
