Slope-intercept form:

y = mx + b "m" is the slope

First i would isolate the "y" in the equation.

2x + y = 4 Subtract 2x on both sides

2x - 2x + y = 4 - 2x

y = 4 - 2x or y = -2x + 4

The given line's slope is -2.

For lines to be perpendicular, their slopes have to be the opposite/negative reciprocals (flipped sign and number)

For example:

slope is 2

perpendicular line's slope is -1/2

slope is -2/3

perpendicular line's slope is 3/2

The given line's slope is -2, so the perpendicular line's slope is 1/2.

Answer: 130

In order to solve for <4, you need to know that supplementary angles add up to 180°.
<3 = 50
180 - 50
130

**For future questions**
1. The sum of the interior angles of a triangle is 180°
2. Alternate interior angles are congruent
3. The exterior angle of a triangle is the sum of the nonadjacent interior angles
