1. The standard form 6x + 2y = -4, when expressed to slope - intercept form is 2. If the graph of a linear equation passes through two points, then the equation is
3. If the graph passes through a point (x1, y1) and has a slope m, then the equation is
4. If the graph of a linear equation has a slope m and a y intercept b then the equation is

no

explanation:

you can be freinds, and people but not follow people.

answer: it depends on what the tax percentage

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
