The slope-intercept form: y = mx + b
We have the slope m = 9, therefore: y = 9x + b.
Next. We have the table:
x | -5 | -2 | 1 | 3 | 4 |
y |-46|-19| 8 |26|35|
(1, 8) → x = 1, y = 8
substitute the values of x and y to the equation:
8 = 9(1) + b
8 = 9 + b |-9
b = -1
Answer: y = 9x - 1 → y-intercept is -1.
If the graph is translated 3 up, reflected across the x-axis, and is narrower than the graph y = x², we have; y = -(x² + 3)
<h3>How to carry out translation of a function?</h3>
We are given the original equation of the function as;
y = x²
Now, when we translate the graph 3 units upwards, it means we add 3 units to the function to get;
y = x² + 3
Now, when we reflect across the x-axis, it means we just change the sign of the function to get;
y = -(x² + 3)
