Answer:
y = -1/2x + 2
Step-by-step explanation:
A line in slope-intercept form in y = mx + b
"m" is the slope
"b" is the y-intercept
x and y represent points on the graph
To write an equation, you need "m" and "b".
We already know m = -1/2
The point (0, 2) is the y-intercept. The y-intercept occurs when x = 0.
Points are in the form (x , y), so x = 0 and y = 2.
Therefore b = 2.
Substitute m = -1/2 and b = 2 into the equation:
y = mx + b
y = -1/2x + 2
Assuming that their exam success is independent then
P(both fail) = 1/4 x 2/5 = 2/20 or 1/10
Answer:
Option A is correct.
Step-by-step explanation:
Given equation is 3x + 4y + 6z = 12
We have to find ordered triplet which indicate where the plane cuts the x-axis.
To find x-coordinate where plane cuts the x-axis we put y and z equal to 0.
3x + 4 × 0 + 6 × 0 = 12
3x + 0 + 0 = 12
3x = 12
x = 4
So, the coordinate where it cuts x-axis is ( 4 , 0 , 0 )
Therefore, Option A is correct.
