Question 675459
First you must convert this into proper equation form: 2y=-4x+7    y= -2x + 3.5 

The "3.5" is considered to be the b in the y=mx+b formula. B is the "y" intercept. Thus, the y intercept is 3.5. 

For the x intercept, you must substitute 0 for y. So the equation reads: 0 = -2x + 3.5. 

Add 2x to both sides: 2x = 3.5  x = 1.75 

The x intercept is 1.75.
