Q1.
The slope-intercept form: y = mx + b
m - slope b - y-intercept
We have the slope m = 5 and y-intercept b = -8. Substitute:
<h3>Answer: D. y = 5x - 8</h3>
Q2.
Choice one point from the graph (look at the picture).
We have the point (2, -1). Put the coordinates of the point to the equations of a line and check the equality.
H. 2x - y = 5
L = 2(2) - (-1) = 4 + 1 = 5
R = 5
L = R CORRECT :)
<h3>Answer: H. 2x - y = 5</h3>
Q3.
The formula of a slope:
We have the points (2, -5) and (6, 3). Substitute:
Therefore we have the answers C and D with that the slope.
Put the coordinates of the points to the equations and check the equality:
C. y = 2x + 12
for (2, -5)
L = -5
R = 2(2) + 12 = 4 + 12 = 16
L ≠ R INCORRECT :(
D. y = 2x - 9
for (2, -5)
L = -5
R = 2(2) - 9 = 4 - 9 = -5
L = R CORRECT :)
for (6, 3)
L = 3
R = 2(6) - 9 = 12 - 9 = 3
L = R CORRECT :)
<h3>Answer: D. y = 2x - 9</h3>
Are you familiar with decimals? It's just an extension of the basic place value you've learned about before. Think of the number 21. "2" is in the tens place, and "1" is in the ones place.
Well, in this question, "1" is still in the ones place. HOWEVER, we have another number AFTER something called a decimal point (.), which shows that now we're getting into digits less than one. "5" is in what's called the tenths place, in which all the numbers are less than one. In other words, 1.5 is equal to 1 + 0.5. 0.5 is less than one, because it is a number in the tenths place.
Obviously, 1+1=2, right? And 2 is less than 3. Well, since 0.5 is even LESS than 1, 1+0.5 is less than 2. Therefore, 1.5 is less than 2, which is less than 3. So, 1.5 is LESS than 3, not greater than.
Answer: No, it's the other way around! 1.5 is LESS than 3.
Answer:
8.6
Step-by-step explanation:
From the above question, we know that the length of the third side is the longest. Hence, we apply Pythagoras Theorem
c² = a² + b²
a = 5, b = 7
c = Third side
c = √a² + b²
c = √5² + 7²
c = √25 + 49
c = √74
c = 8.602325267
Approximately c = 8.6
Possible length of the third side = 8.6
