The y-intercept of the quadratic equation is -47.
<h3>What is Quadratic Equation?</h3>A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
Here, given quadratic equation;
f(i) = i² + 10i - 22
or, y = i² + 10i - 22
y = i² + 2.5x - (47-25)
y = i² + 2.5x + 25 - 47
y = (i+5)² - 47
Thus, the y-intercept of the quadratic equation is -47.

Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given
As we know that the equation of a line in point-slope form is
substituting the values m = -5/4 and point = (8, -9)
Writing the equation in slope-intercept form
where m is the slope, and b is the y-intercept
so the equation of the line in slope-intercept form becomes
subtract 9 from both sides
Therefore, the equation in the slope-intercept form will be:
