Answer:
The solution is (-10,-7)
Step-by-step explanation:
y=2/5x-3 and x=-10
We know x = -10
Substitute the second equation into the first equation to find y
y = 2/5 (-10) -3
y = -4 -3
y = -7
The solution is (-10,-7)
Gradient = 
This means the gradient is 4x.
The y intercept is where the line crosses the y axis. We can see this is at -3.
<h2>
Rule: <u>y = 4x -3</u></h2>
Substitute your values to check if it's right.
y = 4x -3
5 = 4(2) - 3
5 = 8 - 3
5 = 5
1 = 4(1) - 3
1 = 4 - 3
1 = 1
