Hey there :)
To find the slope with <em>two points</em> we will need to use the equation
( 3 , -20 ) ( 5 , 8 )
Here is what the equation should look like when replaced with the numbers (<em>it will be a fraction</em>) :
We know that <em>two negatives</em> cancel out and make a positive, so the numerator would actually be 8 + 20.
Solve the fraction and we get
28 <em>divided</em> by 2 is 14. The slope is 14.
Hey!
------------------------------------------------
Points:
(-2, 3) and (3, 0)
------------------------------------------------
Find the slope:
------------------------------------------------
Slope Intercept Form:
y = mx + b
m = slope
b = y-intercept
Slope = -3/5
Y-intercept = 9/5
Answer: y = -3/5 + 9/5
------------------------------------------------
Point Slope Form:
y - y1 = m(x - x1)
You can use either of the points.
Answer:
y - 3 = -3/5(x - 2)
or
y - 0 = -3/5(x - 3)
------------------------------------------------
Hope This Helped! Good Luck!
The solution of 0.6(4-2x)=20.5-(3x+10) is x = 4.5
<u>Solution:</u>
Given, expression is 0.6 ( 4 – 2x ) = 20.5 – ( 3x + 10 )
We have to solve the above given equation for x.
Now, take the equation
We have to use BODMAS rule. BODMAS means sequence of operations which is brackets, order, division, multiplication, addition and then subtraction
On solving the brackets, we get
Now multiplication is given preference
Now subtraction is done
Now division is performed
Hence, the value of x is 4.5
