Part 1: The equation of the line is $y=2x+1$

Part 2: The equation of the line in slope intercept form is $y=-3x-1$

Explanation:

Part 1: It is given that the point A is $(1,3)$ and the line B is $y=2 x-2$

To determine the line passing through the point A and parallel to line B, let us first determine the slope and y-intercept.

From the equation of line B, the slope is $m=2$

Substituting the point $(1,3)$ and $m=2$ in slope intercept form $y=mx+b$ , we have,

$3=2(1)+b$

$3=2+b$

$1=b$

Thus, the y-intercept is $b=1$

Let us substitute the values $m=2$ and $b=1$ in the slope intercept form $y=mx+b$ , we get,

$y=2x+1$

Thus, the equation of the line passing though point A and parallel to line B is $y=2x+1$

Part 2: The given two coordinates are $(-1,2)$ and $(1,-4)$

To determine the equation of line in slope intercept form, first we shall find the slope and y-intercept.

From the graph, we can see that the line touches the y-axis at -1.

Hence, the y-intercept is $b=-1$

The formula for slope is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substituting the coordinates $(-1,2)$ and $(1,-4)$ , we have,

$m=\frac{-4-2}{1+1} =\frac{-6}{2} =-3$

Thus, the slope is $m=-3$

Substituting the values $b=-1$ and $m=-3$ in the slope intercept formula $y=mx+b$ , we get,

$y=-3x-1$

Thus, the equation of the line in slope intercept form is $y=-3x-1$

URGENT PLS RESPOND!!!

Elan Coil [88]

Answer:

$\huge\boxed{d=\sqrt{17}}$

Step-by-step explanation:

Simply use the fact that the change in x squared + the change in y squared = the distance squared. (The Pythagorean Theorem)

1^2 + 4^2 = d^2

1 + 16 = d^2

17 = d^2

d = √17

Hope it helps :)

Solve. 2 (x - 1/2) = 3 (5 - 2x) show the steps in your solution.

viktelen [127]

Question 1.). Solve:

2 (x - 1 / 2) = 3 (5 - 2x)

Simplify both sides of equation:

2( x - 1 / 2 ) = 3(5 - 2x )

(2) (x) + (2) ( -1 / 2 ) = (3) (5) + (3) ( -2x )

Distribute:

2x + - 1 = 15 + -6x

2x - 1 = -6x + 15

Add 6x to both sides:

2x - 1 + 6x = -6x + 15 + 6x

8x - 1 = 15

Add 1 to both sides:

8x - 1 + 1 = 15 + 1

8x = 16

Divide both sides by 8:

8x / 8 = 16 / 8

Answer: 2 (x - 1 / 2) = 3 (5 - 2x) ==========> x = 2

Question 2.).

M =======> Amount Malik need

Solution: =========> m ≥ 5

Inequality ========> 8 + 7 + 10 + m ≥ 30

25 + m ≥ 30

Interpretation ==========> Malik needs at least, $5 .00 to get to, $30.00 or more.

Is the solution reasonable ===========> YES

Hope that helps!!!!! : )
