Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
You know:
m = 3
b = -2 So substitute/plug it into the equation
y = mx + b
y = 3x + (-2)
y = 3x - 2 Your answer is the 2nd option
You can find the slope of a linear function by taking two points and finding the change in y over change in x.
Hm, but the values you gave for the tables don't make sense for a linear function/relationship. But let's just pick two points as an example.
So two points you can pick are (-2, 13) and (1, -3).
The slope, change in y over change in x is in other words (y2 - y1 / x2 - x1), where (x1, y1) is one point and (x2, y2) is another.
(-3 - 13) / (1 - -2) = -16/3 = -(16/3)
Or you could have switched up the order of those coordinates but you still get the same answer.
(13 - -3) / (-2 - 1) = 16 / (-3) = -(16/3)
Use your fingers.
Hold down the first finger on your left hand, nine fingers remain up. The answer is 9
For two hold down the second finger on your left hand. On the left is one finger standing, and on the right are 8 fingers standing. The answer is 18
This pattern works for everything up to ten. Then you remember 9 x 11 is 99. And 9 x 12 is 108
Answer:
Solutions: (-2. -6), (1, -2), (10, 3), (5, 3)
Step-by-step explanation:
Answer:
4/9
Step-by-step explanation:
using cross canceling you see
(4(5)(6)(7)(8))/(5(6)(7)(8)(9))
everything cancels except for the 4 on top and the 9 on the bottom so
4/9
