Answer:
- gradient is 4.
- y-intercept is -5.
- No.
Step-by-step explanation:
1. In order to find the gradient of equation, you have to make it into slope-form equation y = mx + b :
So m represents gradient. In this question, m is 4.
2. Make it into slope-form equation :
In this question, y-intercept is b which is -5.
3. You have to substitute x-coodinate into the equation to see whether it is equal to y-coordinate :
