Answer:

y=4x-2

Step-by-step explanation:

for every 1 unit increase in x, y values change by a factor of four units

slope=4x

f(x)=y

y=mx+b

2=4(1)+b

b=-2

equation= y=4x-2

CHECK

6=4(2)-2

6=8-2

6=6

CORRECT

10=4(3)-2

10=10

CORRECT

alternatively... (y2-y1)/(x2-x1)

(6-2)/(2-1)= (4)/(1)

slope=4

Find the slope of a line that passes through the given points. Write your answer below.
12345 [234]
Just use the formula:
slope(m) = \frac{y_2-y_1}{x_2-x_1}

Then, plug in numbers:
m = \frac{1-4}{-2-3} = \frac{-3}{-5} = \frac{3}{5}

And that would be your answer: 3/5 is the slope.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
REY [17]

Answer:

x=\sqrt{10}

Step-by-step explanation:

The given equation is :

5-2x^2=-15

We need to solve it using inverse operations.

Subtract 5 from both sides of the equation.

5-2x^2-5=-15-5\\\\-2x^2=-20\\\\2x^2=20\\\\x^2=10\\\\x=\sqrt{10}

So, the solution of the given equation is x=\sqrt{10}.
