Using the slope intercept form of y = mx + b
the "b" is the spot where it crosses the y axis....in your equation, it crosses the y axis at -3.
Answer:
Hello answer =9/40
Step-by-step explanation:
1. Find the reciprocal of the fraction.
(BTW this turns it into a multiplication problem)
2. Afterwards you multiply them together.
WORK:
<u>2 </u> divided <u>5</u>
16 6
<u>2 </u> times 6
16 5
Cross divide 2 from 16 and 6
Multiply across
GEt your answer:)
I hope this helps:) You can use mathaway to check your answer
Question:
Find the gradient of the line passing through (6,8) and (4,10).
Answer:
-1 is the right answer.
Step-by-step explanation:
Slope of the line = The gradient of the line
Gradient of the line is known as change in the value of y-axis by change in the value of x-axis
Gradient = ∆y\∆x

Answer:
The Area of Δ ABC = 219.13
Step-by-step explanation:
<em>The hard part about this problem is finding the area without the height</em>
The formula to do this is Area = 
A, B, C represent the sides
S represents
(A + B + C)
In this equation, we will make the base be A, and the other two sides will be B and C
<u>Sides B and C are the same length</u> because they meet at a 90° angle
Lets plug the numbers into the variables
A = 28
B= 21
C= 21
<u>Remember:</u> S represents
(A + B + C)
S =
(28 + 21 + 21)
S =
(70)
S = 35
<em>Lets plug the numbers into the Area Formula now!</em>
Area = 
According to the order of operations, we need to do the calculations in parentheses <u>first</u>
35 - 28 = 7
35 - 21 = 14
35 - 21 = 14
14 x 14 x 7 = 1372
1372 x 35 = 48020
= 219.13
The Area of Δ ABC = 219.13
