y = 1/7x + 4

1/7 * a2 = -1

a2 = -7

y = -7x + b

A = (-1, 5)

-7 * (-1) + b = 5

7 + b = 5

b = -2

<em><u>y </u></em><em><u>=</u></em><em><u> </u></em><em><u>-7x </u></em><em><u>-</u></em><em><u> </u></em><em><u>2</u></em>

Describe how you would determine the x-intercepts from the factored form of a quadratic equation
Aloiza [94]

Answer:

Please check explanations

Step-by-step explanation:

Given the factored form, all we have to do is to equate each of the factor to zero, then solve for x

The particular value of x represents the solution that shows the value of the x-intercept

for example

In a case of a quadratic equation where we have

(x-a)(x-b) = 0

Then we can have

(x-a) = 0 or ((x-b) = 0

Then we have x = a or x = b

a and b are the x intercepts in this case
