The figure shows that l1 is parallel to l2 and l3 is a transversal. The angle marked x measures:
150o.
130o.
100o.
50o.
The straight line that passes through the point (1, 3) and has gradient -2 is:
y = -2x + 5.
y = −2x − 5.
y = 2x − 5.
y = 2x + 5.
Given the lines
L₁: y = -3x + 3 and
L₂: y = mx - 2 such that L, is parallel to L₂, the value of m is:
-3.
3.
3/2.
⅓.
Given that the lines 3x + 6y + 5 = 0 and 2x + ky -13 = 0 are parallel, the value of k is:
1/2.
2.
-1.
4.
Given that l₁ and l₂ are parallel lines in the figure, and I₃ is a transversal with angle b = 85°,the value of angle a is:
85°.
95°.
125°.
175°.
