The slope of the line is 2. The y-intercept will be equal to -4 or 4 units (absolute value). The solution of the system of equations will be (2,0).

Given information:

The linear function is y = -x + 2 .

Other linear function passes through the points (–2, –8) and (1, –2).

Now, the slope of the function passing through (–2, –8) and (1, –2) will be,

$m=\dfrac{-2-(-8)}{1-(-2)}\\m=\dfrac{6}{3}=2$

So, the slope of the line is 2.

Now, the equation of the line will be,

$y-(-8)=2(x-(-2))\\y+8=2x+4\\y=2x-4$

From the above equation of the line, the y-intercept will be equal to -4 or 4 units (absolute value).

The graph of the system of lines is attached as an image in the solution.

The point of intersection of the two lines will be the solution of the system. So, the solution will be (2,0).

Answer from: jayceerocks5614

Part 1) m=2

Part 2) The y-intercept is the point (0,-4)

Part 3) The solution of the system is (2,0) (the graph in the attached figure)

Step-by-step explanation:

Part 1) What is the slope of the linear function that passes through the points (–2, –8) and (1, –2)?

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{-2+8}{1+2}$

$m=\frac{6}{3}$

m=2

Part 2) What is the y-intercept?

Find the equation of the line in slope intercept form

y=mx+b

we have

m=2

$point\ (1,-2)$

substitute and solve for b

$-2=2(1)+b\\b=-4$

y=2x-4

The y-intercept is the point (0,-4)

Part 3) Graph the linear function to determine the solution. What is the solution?

we have

y=-x+2 ----> equation A

y=2x-4 ----> equation B

Solve the system by graphing

The solution is the intersection point both graphs

using a graphing tool

The solution of the system is (2,0)

Answer from: Quest

$655.61 which is option c

step-by-step explanation:

price of house = $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

= $\frac{3.5*146000}{100}$

=$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

=$35770

remaining money = $146000-35770

=$110230

new mortgaged payment = 5 % of 110230

= $\frac{5*110230}{100}$

=$655.61
