What about lesson 6.2 math 7th grade??
(-7,8)
Simplifying 2(x+7)^2+8
Will give you the image results
You must graph the formula and you’ll get -7,8 (using desmos helps)
Answer:
See below

Answer:
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
Step-by-step explanation:
<u>Let's convert the standard equation into slope-intercept form:</u>
- Ax + By = C ⇒ subtract Ax from both sides
- By = -Ax + C ⇒ divide both sides by B
- y = -A/Bx + C/B ⇒ converted to slope- intercept form
As we see the slope is -A/B
<u>The equation 7x + 9y = 14 is converted as:</u>
- y = -7/9x + 14/9, where the slope is -7/9
<u>Looking at the answer options and the correct one is option B, where both identification of slopes match.</u>
- B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
