Question

given linear equation y=-3/2x+1 find the y- coordinates of the points(-4), (-2) and (6). Please show all of your work. Plot those points and graph the linear equation.

Answer 1

For x = -4:
y=-3/2(-4)+1
y=12/2+1
y=6+1
y=7

For x = -2:
y=-3/2(-2)+1
y=6/2+1
y=3+1
y=4

For x = 6:
y=-3/2(6)+1
y=-18/2+1
y=-9+1
y=-8

From the equation, it can be seen the y-int is 1.
From the equation, it can be seen the x-int is 2/3.
