Find the gradient of the line 2y -8x = -2 Find the y-intercept of the line 3y=-15x -15
Does the point (3,15) lie on the line y=10+2x?
25 points to whoever answers all of them

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 :

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
