Answer:
The Y intercept would be 1. The slope would be 2.
Step-by-step explanation:
The Y intercept is where a line intercepts, or crosses the Y axis. As you can see in the graph, the line crosses the Y axis at point 1.
To find slope here, you can do the rise divided by the run.
To find this, choose two points. We can use point (0, 1) and point (1, 3)
Next, find the rise, or the vertical distance between the two points. In this case, it would be 2.
Then, find the run, or the horizontal distance between the two points. In this case, it would be 1.
Finally, divide the rise by the run, and create the fraction rise over run, or in this case 2/1.
Explanation:
Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.
The actual slope is ...
slope = Δy/Δx = 6/2 = 3
Answer:1375
Step-by-step explanation:
X= 15 is given
X squared is 15x15 = 225
1600 - 225= 1375
Answer:
Step-by-step explanation:
Δy =-4-1 = -5
Δx =-8-(-6) = -2
distance = √((Δx)^2+(Δy)^2) = √(4+25) = √29
Answer:
The measure of angle B is 68° and the measure of angle C is 22°
Step-by-step explanation:
we know that
If two angles are complementary, then their sum is equal to 90 degrees
m∠B+m∠C=90° -----> equation A
m∠B=3(m∠C)+2 ----> equation B
Substitute equation B in equation A and solve for m∠C
3(m∠C)+2+m∠C=90
4(m∠C)=90-2
4(m∠C)=88
m∠C=88/4
m∠C=22°
Find the value of m∠B
m∠B=3(22)+2=68°
therefore
The measure of angle B is 68° and the measure of angle C is 22°
