Answer:
y=-2x+5
Slope: -2
y int. 5
Step-by-step explanation:
Convert to slope intercept form
2y-10=-4x
Add 10 to both sides
2y-10+10=-4x+10
Simplify
Divide both sides by 2

Simplify
y=-2x+5
Slope: -2
y intercept: 5
Answer:
y=4x-2
Step-by-step explanation:
if slope is 4, gradient is 4 so y=4x +c
given y intercept of -2,, y=4x -2
c=-2
