Answer:
y = -⅓x + 7
Step-by-step explanation:
Given the two points that lie on the line (3, 6) and (-3, 8), we can find the equation without the grid by finding the slope (m) and y-intercept (b).
The equation would be written in the form of y = mx + b (slope-intercept form):
✔️Find m:
Slope (m) = change in y/change in x
Slope using (3, 6) and (-3, 8), would be:
Slope (m) = (8 - 6)/(-3 - 3) = 2/-6
m = -⅓
✔️Find b:
Substitute (x, y) = (3, 6) and m = -⅓ into y = mx + b to find b
6 = -⅓(3) + b
6 = -1 + b
6 + 1 = b
b = 7
✅Write the Equation:
Substitute m = -⅓ and b = 7 into y = mx + b
Thus,
y = -⅓x + 7
Answer:
x = 1/3
One-third
Step-by-step explanation:
3(x-1) -2(2x+1) = 8(x-1)
3x-3-4x-2=8x-8
-x-5=8x-8
Collect like terms
-x-8x=5-8
-9x=-3
Divide both sides by -9
x = 3/9
= 1/3
The best choice is A) Blake should not include the outlier because it overstates the effect of rainfall on temperature.
