Answer:

True

Step-by-step explanation:

To determine if (5, - 2 ) is a solution to the system , substitute the values of x and y into the left side of both equations and if equal to the right side then it is a solution.

5(5) - (- 2) = 25 + 2 = 27 = right side

- 3(5) + 4(- 2) = - 15 - 8 = - 23 = right side

the point (5, - 2 ) makes both equations true then is a solution to the system.

Can someone help please?

Katarina [22]

Answer:

g = 6

Step-by-step explanation:

To find the slope you do:

m = change in y ÷ change in x or (y2 - y1) ÷ (x2 - x1)

x1 = 4, y1 = -7
x2 = g, y2 = -3
m (the slope) = 2

Sub in the values:

2 = (-3 - -7) ÷ (g - 4) - we can simplify this

2 = (4) ÷ (g - 4)

4 divided by what gives us 2? 2. This means that g - 4 = 2, g = 2 + 4 which is 6:

g = 6

Hope this helps!
