Enter the equation of the line which passes through the points (0,−3) and (2, 1)
1 answer:
Answer:
y = 2x -3
Step-by-step explanation:
The formula for the equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept of the line. I will be calculating the slope of the line using the points (0, 3) and (2, 1)
Slope =
=
=
=
= 2
The y-intercept is the point on the y-axis when the point on the x-axis is 0. Based on the point (0, -3), you can see that the point on the y-axis, while the point on the x-axis is 0, is -3. Thus, the y-intercept is (-3).
Overall, the equation of the line is: y = 2x-3

Trapezoid JKLM is shown below.
What is the length, in centimeters, of KL ?
A. 12 cm
B. 10 cm
C. 9 cm
D. 6 cm
The mentioned figure is attached.
Answer:
Explanation:
1. KL is the hypotenuse of a right triangle; hence, you can use Pythagora's theorem to find its length.
2. The height 8 cm is one leg of the right triangle.
3. The other leg may be found by difference:
4. Now you can use Pythagora's theorem:
