Find the coordinates of the point where the line <img src="https://tex.z-dn.net/?f=y%3D5x%2B7%5C%5C" id="TexFormula1" title="y=5

Anvisha [2.4K]

Answer:

(0, 7)

Step-by-step explanation:

The point that crosses the y-axis is called the y-intercept of the line.

We are given an equation of the line and we need to determine the y-intercept. This can be done by determining the constant in the equation.

What are constants?

Constants are such terms that include only numbers. There should be no variables in constants.

<u>We know that:</u>

$\bullet \ \text{Given equation of line: y = 5x + 7}$

The constant we can see in the equation is "7". Therefore, the y-intercept is 7.

Note: The y-intercept of the line must have an x-coordinate of 0.

<u>Therefore,</u>

⇒ Coordinates of y-intercept: (x, y) ==> (0, 7).

If k = -3 what is the value of k + (2k - 10) ?<br><br> A. –19<br> B. –7 <br> C. 1<br> D. –14

gladu [14]

Answer:

A

Step-by-step explanation:

We have the expression $k+(2k-10)$

We want to find the value when k is -3. So, substitute -3 for k and evaluate:

$\Rightarrow (-3)+(2(-3)-10)$

Multiply:

$=-3+(-6-10)$

Subtract:

$=-3+(-16)$

Add:

$=-19$

Therefore, our answer is A.
