Answer:
x=2/3, y=0
Step-by-step explanation:
3x + 7y = 2,
6x - 5y = 4
Make the x coefficient the same in both equations.
3x + 7y = 2
(whole thing multiplied by 2)
6x + 14y = 4
Now subtract the equations to eliminate the x variable.
6x + 14y = 4
-(6x - 5y = 4)
19y = 0
<u>y = 0</u>
Substitute 0 for y in one of the equations.
3x + 7(0) = 2
3x = 2
<u>x = 2/3</u>
2/7y + 5 = 9
Subtract 5 from both sides
2/7y = 4
Multiply both sides by 7
2y = 28
Divide both sides by 2
<em><u>y = 14</u></em>
Answer:
(-2,3)
so the a answer is -2 on the x axis
Answer:
Step-by-step explanation:
a) The y-coordinates of points A and B are both -2, so there is no change in the y-value between those points. The x-coordinates differ by 4, so the slope is ...
... slope = (change in y)/(change in x) = 0/4 = 0
b) The y-value is constant at -2 for any value of x, so the equation of the line is ...
... y = -2
