Answer:
Step-by-step explanation:
Equation of a line is given as 
Where,
m = slope of the line = 
b = y-intercept, which is the value at the point where the line intercepts the y-axis. At this point, x = 0.
Let's find m and b to derive the equation for the line.
Use the coordinate pair of any two points on the line. Let's use the following,
=> on the line, when x = 0, y = -2
=> on the line, when x = 4, y = 1
Plug in the values and solve for m
b = -2 (the line intercepts the y-axis at this point)
Our equation would be =>
Answer: Therefore it must be the first one, 40
Step-by-step explanation: Vertical angles are always congruent, which means that they are equal. x = 40
Answer:
0 and 1
Step-by-step explanation:
Answer:
x=20
Step-by-step explanation:
just use the pythagorean theorem!!
square 12 and 16 to get 144 and 256
add those together to get 400, and then just take the square root of 400 (which is 20)
this means that x=20!
hope this helps!! :)
