Answer:

slope = $\frac{23}{21}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (18, 26)

m = $\frac{26-3}{18+3}$ = $\frac{23}{21}$

Show me how to make a 10 to solve 13-7

evablogger [386]

If you are talking about building blocks, then you would get one 10 and 3 ones, then subtract that from 7 ones and would get 6

Solve x=7-2t for t.

yuradex [85]

x=7-2t

Move 7 to the other side. Sign changes from +7 to -7.

x-7=7-7-2t

x-7=-2t

Divide by -2 for both sides

x/-2-7/-2=-2t/-2

x/2+7/2=t

Answer: t= x/2+7/2 or t=7/2+x/2

Graph and write solution: 2x + 1 = y -4x + 6y = -10

PIT_PIT [208]

The graph is shown in figure below

The Solution Set is (-2,-3)

Step-by-step explanation:

We need to graph the equations and writ the solution.

For graphing we need to find the values of x and y.

For that, we need to solve the given equations:

$2x + 1 = y\\-4x + 6y = -10$

Let:

$2x + 1 = y\,\,\,eq(1)\\-4x + 6y = -10\,\,\,eq(2)$

We can solve this by using Substitution Method.

Putting value of y of eq(1) into eq(2) and finding value of x:

$2x + 1 = y\,\,\,eq(1)\\-4x+6(2x+1)=-10\\-4x+12x+6=-10\\8x+6=-10\\8x=-10-6\\8x=-16\\x=-16/8\\x=-2$

So, value of x = -2

Now put value of x in eq(1) to find value of y:

$2x + 1 = y\\2(-2)+1=y\\-4+1=y\\y=-3$

So, value of y = -3

Plotting on graph: x=-2 and y = -3

The graph is shown in figure below

The Solution Set is (-2,-3)
