\begin{aligned} &amp;-5y=-5 \\\\ &amp;7x+6y=7 \end{aligned}
SSSSS [86.1K]

Answer:

(5,1) is not a solution of the above system of equations.

Step-by-step explanation:

We are given a system of equations that are  

- 5y = - 5 ......... (1) and  

7x + 6y = 7 ........... (2)

So, solving equation (1) we get y = 1 and putting y = 1 in the equation (2) we get 7x = 7 - 6(1) = 1

⇒ x = \frac{1}{7}

So, it clear from the solution of the above equations i.e. (\frac{1}{7}, 1), we can say that (5,1) is not a solution of the above system of equations. (Answer)

Plot the line for the equation on the graph. y-5=3/2(x-2)?
never [62]

Answer:

See the attachment

Step-by-step explanation:

The equation is in point-slope form, so you can read from the equation that one of the points on the graph is (2, 5).

The slope of 3/2 tells you that going 2 units to the right (to x=4) will move the point up 3 units (to y=8).

You can draw your line through these two points: (2, 5) and (4, 8).
