Answer:
x = ± 13
Step-by-step explanation:
Given
x² = 169 ( take the square root of both sides )
x = ±
= ± 13
Since 13 × 13 = 169 and - 13× - 13 = 169
Answer:
y =
+ 2
Step-by-step explanation:
The y-intercept of the line is (0,2)
The slope of the line is
We derive the slope of a line by dividing the change in y by the change in x
So,
= 
y - 2 =
The equation of the line therefore is;
y =
+ 2
