<em><u>Complete Question:</u></em>
What is the y intercept of y = -3-7x
<em><u>Answer:</u></em>
<h3>The y intercept is (0, -3)</h3>
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>
y = -3 - 7x
The y intercept is the point where the line crosses the y axis
<u>Finding y intercept:
</u>
To determine the y-intercept, we set x equal to zero and solve for y
Substitute x = 0 in given equation
y = -3 - 7(0)
y = -3 - 0
y = -3
Thus the y intercept is (0, -3)
Answer:
- B. 2 x minus z minus 5 + 2 z squared
Step-by-step explanation:
<u>Conditions:</u>
- The x-term has a coefficient of 2,
- The z-term has a coefficient of -1.
- The expression has a constant term less than zero
<u>Answer options:</u>
A. 2 x + z + 5 minus 6 z squared ⇒ 2x +z+5-6z²
- Incorrect. Only the first condition is met
B. 2 x minus z minus 5 + 2 z squared ⇒ 2x-z-5+2z²
- Correct. All 3 conditions met
C. Negative 2 x minus z minus 5 + 2 z squared ⇒ -2x-z-5+2z²
- Incorrect. The first condition is not met
D. Negative 2 x + z minus 5 + 2 z squared ⇒ -2x+z-5+2z²
- Incorrect. Only the third condition met
