To find the slope between two coordinates, you use the formula:
m = y2 - y1/x2 - x1
If coordinate A is (-2, 5) and coordinate B is (3, -4), then:
y2 = -4
y1 = 5
x2 = 3
x1 = -2
So, just substitute the points into the formula.
m = -4 - 5/3 - (-2)
m = -9/5
The slope of the line is -9/5.
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

Hello!
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Now, we first can find the slope. We know the line is parallel to y = 2/5x - 2, and parallel lines <u>always have the same slope.</u> Therefore, we now know that the slope (or m) is 2/5. Substitute that in the equation.
y = 2/5x + b
Finally, we are given a point. We can substitute (-5, -3) into the equation, and then solve for b.
x = -5, y = -3
-3 = 2/5 (-5) + b
-3 = -2 + b
-1 = b
Now, we know what b is. Substitute this into the equation.
Therefore, y = 2/5x - 1 is our final equation.
Hope this helps!
Answer:
x=√154 over 7 , −√154 over 7
Step-by-step explanation:
Answer: 10 minutes
Step-by-step explanation:
Let x be minutes.
Toatl costs for a call are:
A: 35 + 3x
B: 45 + 2x
When will A = B?
35 + 3x = 45 + 2x
1x = 10
They are equal cost at 10 minutes
