Question

What is the answer to this?

Answer 1

Explanation:

We know that:

• The y-intercept of an equation is the constant.
• Constants are the numerals in the equation.

Finding the y-intercept.

In the equation provided, we can see only one constant.

• => y = 1x² + 7x - 5

Thus, the y-intercept is -5.

Answer 2

To find the y-intercept substitute x as 0

$y = 1 \times {0}^{2} + 7 \times 0 - 5$

$y = 1 \times 0 + 0 - 5$

$y = 0 + 0 - 5$

$y = - 5$

• Thus, The y-intercept is -5...~
