Find the difference of (t-8)-(t-15)

The slope of a line is –2 and its y-intercept is (0, 3). what is the equation of the line that is parallel to the first line and passes through (2, 2)? a. 2x + y = 6 b. y = –2x + 3 c.y=1/2x +6 d.y=-2x-6

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

What is the result of adding the system of equations? 2x+y=4 3x-y=6
