Means, for every 1 input, there is 1 coresponding output
normally x is input and y is output in form (x,y)
so just look for the option(s) that has/have every first number repeat with only 1 2nd number
A. -7 repeats with 5 and -3, not a function
B. no repeats of first number (6,-8) and (-5,-8) are fine because first numbers don't repeat, das is funciton
C. no repeats, function
D. no repeats, function
answer is B,C,D
Answer:
Slope = 2
Y-Intercept = 4
Equation of Line is y=2x+4
Step-by-step explanation:
y-intercept is the point in the y-axis, where the line cuts it. So, looking at the graph, the y-intercept would be y = 4
To figure out the slope, we take any two points and calculate using the formula:
Where, m is the slope
is the first coordinate, and
is the second coordinate
<em>Let's take two points as: (-2,0) & (-1,2)</em>
<em />
Plugging these into the formula we get the slope as:
Hence slope is 2
Equation of the line is given as y = mx + b, where m is the slope (in our case 2) and b is the y-intercept (in our case 4). Thus:
Equation of Line:
Answer:
I believe the first question is the third option. I hope this helps!
Answer:
150
Step-by-step explanation:
360 - (130 + 80) = 150
