Answer:
Angle 1 and 2 = 180 which is a straight line angle
3 and 4 also = 180
1angle + 2angle + 3angle + 4angle = 360 degrees
Step-by-step explanation:
I need help i literally don't understand any of these questions
Answer: It is below with explanations on how to do it! :D
Step-by-step explanation:
1. First one shows a graph and a line. Remember, the equation for this is y = mx + b. The point that crosses the y-axis is 0. So far, the equation looks like this: y = mx + 0. In order to find the slope, we have to choose another point on the graph. I will choose the point (-4, -2). The slope is the direction of the line travelling from left to right. So to get from (-4, -2) to the point 0, aka origin, we have to go up 2 units and move 4 units to the right. This method is called rise over run. Now the slope is 2 over 4 -> 2/4.
Final answer is y = 2/4x + 0
Simplified version is y = 1/2x + 0
That is your equation in slope intercept form!
2. The second one shows a graph and is asking to write an equation in slope-intercept form. Here is the equation for that -> y = mx+b
M is the slope, and b is the y-intercept (where the point crosses the line on the y-axis).
So, in this case, M=4 and b=0
Plug it into the equation, y = 4x + 0
The graph is attached below (I did not draw it but I took a screenshot from a video that shows it)
I also attached the graph for you for the last question!
I hope this helps you :)
