The y-coordinates of point A and B are:
Point A (4, 5.6) 1.4*4 = 5.6
Point B (-6, -8.4) 1.4 * -6 = -8.4
Answer:
No
Step-by-step explanation:
We can plug in the ordered pair (6,-1) into the equation. Remember that 6 is the x coordinate therefore we plug it in for x and that -1 is the y coordinate so we should plug it in for y.
6x+3y=6(6)+3(-1)=36-3=33
Since 33 is not equivalent to 15, (6, -1) is not a solution to the equation.
