Question

y=x−1

−3x+2y=4

Answer 1

y=x-1

-3x+2y=4

2y= 3x+4

y =3x/2 +2

3x/2+2 = x-1

x/2 =-3

x =-6

y=-7

the point (-6,-7) is the intersection of the two lines

y=x-1 is an upward sloping line with slope = 1 and y intercept =-1

y=3x/2+2 is an upward sloping line with slope = 3/2 and y intercept =2

they intersect in quadrant III where both x and y are negative

plot the points and graph the lines
