To find the y-intercept substitute x as 0

[tex]y = 1 \times {0}^{2} + 7 \times 0 - 5[/tex]

[tex]y = 1 \times 0 + 0 - 5[/tex]

[tex]y = 0 + 0 - 5[/tex]

[tex]y = - 5[/tex]

  • Thus, The y-intercept is -5...~

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.
