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.
The gradient of the line 3y = 6x - 3 is:
2.
6.
-2.
-1.
The y-intercept of the line y = 2x + 4 on the cartesian plane is:
4.
-4.
What are transversal lines?
All are correct.
Lines that cut other lines (usually parallel lines) at an angle other than right angle.
Lines that intersect to form a right angle at the point of intersection.
None is correct.
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°.
175°.
95°.
125°.
