Find the gradient and y-intercept in this equation:

Gradient: -4

y-intercept:

Step-by-step explanation:

Step 1 - Subtract 8x from both sides to isolate the 2y + 9

Step 2 - Subtract 9 from both sides to isolate the 2y:

Step 3 - Divide both sides of the equation by 2:

In this form, y = mx + b, the m value is the gradient with the b value being the y-intercept. This means:

Resulting in the gradient being -4 and the y-intercept being .
