Answer:

y=3x-8

Step-by-step explanation:

find the slope by using the slope formula: y2-y1/x2-x1 so 4-1/4-3 solve 3/1 so the slope is 3. standard lines are y = mx+b plug it in with one of the points: 4= 4(3) + b the m is the slope and I plugged the x and y points 4 into it. 4=12+b subtract 12, b=-8 that is the y intercept.

check 1=3(3) + b, 1= 9 + b, -8= b:

so the y intercept is -8 the slope is 3 now we replace it to get a linear equation;

y=3x-8

Answer:

The equation of the line that passes through the points (3,1) and (4,4) is (3x-y=8).

Step-by-step explanation:

Given ; (x_1,y_1),(x_2,y_2)=(3,1) , (4,4)

Equation of the line that passes through the points can be determined by using point slope form equation of line;

(y-y_1)=m\times (x-x_1)

slope of the line = m

m=\frac{y_2-y_1}{x_2-x_1}=\frac{4-1}{4-3}=\frac{3}{1}

(y-1)=3(x-3)

y-1=3x-9

3x-y=9-1

3x-y=8

The equation of the line that passes through the points (3,1) and (4,4) is (3x-y=8).

Which statements are true about the ordered pair (10, 5) and the system of equations?
Alexeev081 [22]

Answer:

C

Step-by-step explanation:

We have the system of equations:

\left\{\begin{array}{ll}2x-5y=-5 \\ x+2y=11\end{array}

And an ordered pair (10, 5).

In order for an ordered pair to satisfy any system of equations, the ordered pair must satisfy both equations.

So, we can eliminate choices A and B. Satisfying only one of the equations does not satisfy the system of equations.

Let’s test the ordered pair. Substituting the values into the first equation, we acquire:

2(10)-5(5)\stackrel{?}{=}-5

Evaluate:

20-25\stackrel{?}{=}-5

Evaluate:

-5\stackrel{\checkmark}{=} -5

So, our ordered pair satisfies the first equation.

Now, we must test it for the second equation. Substituting gives:

(10)+2(5)\stackrel{?}{=} 11

Evaluate:

20\neq 11

So, the ordered pair does not satisfy the second equation.

Since it does not satisfy both of the equations, the ordered pair is not a solution to the system because it makes at least one of the equations false.

Therefore, our answer is C.
