Answer:
y = 1.6x + 3.4
Step-by-step explanation:
We have to use the equation y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y-intercept
<u>First, let us find the slope.</u>
For that, we can use the given two coordinates.
( -1 , 5 ) ⇒ ( x₁ , y₁ )
( 4 , -3 ) ⇒ ( x₂ , y₂ )
The <u>formula to find the slope</u> of a line is :
m = ( y₁ - y₂ ) ÷ ( x₁ - x₂ )
<u>Let us solve now.</u>
m = ( y₁ - y₂ ) ÷ ( x₁ - x₂ )
m = ( 5 - ( -3 ) ) ÷ ( -1 - 4 )
m = ( 5 + 3 ) ÷ -5
m = 8 ÷ -5
<u>m = -1.6</u>
Now let us<u> find the y-intercept (c )</u> of the line.
For that, let us get one of the coordinates which are given in the question.
I'll get ( -1 , 5 ) from that.
( -1 , 5 ) ⇒ ( x , y )
<u>Let us solve now.</u>
y = mx + c
5 = -1.6 × -1 + c
5 = 1.6 + c
5 - 1.6 = c
<u>3.4 = c</u>
Therefore,
m ⇒ -1.6
c ⇒ 3.4
So, the equation of the line is :
y = mx + c
<u>y = 1.6x + 3.4</u>
Answer:
B
Step-by-step explanation:
Hope this helped that's all.
The definition of parallel lines states that they don't intersect, so that would always be true. (In Euclidean geometry, anyway.)
Answer:
12/20
Step-by-step explanation:
John scored =12 points
His tries =20 tries
Probability = number of favourable outcomes / no. of all possible outcomes
Probability = 12/20
=3/5
