Step-by-step explanation:
y = -3x - 4
Given the linear equation, y = -3x - 4, where:
m (slope) = -3
b (y-intercept) = -4
Since we already have the y-intercept, (0, -4), we can start plotting points into the graph using the slope, 
(which also represents three units down, 1 unit to the right).
I have no idea she got it wrong the real answer is 5
Answer:
b.) 2
Explanation:
Parallel slopes have same slope.
Perpendicular slopes have negatively inverse slope.
Comparing it with slope intercept form, "y = mx + b" where m is slope.
Here parallel slope: -1/2
Perpendicular slope: -(-1/2)⁻¹ = 2
Answer:
Minimum
Step-by-step explanation:
A minimum occurs when the line goes from decreasing to increasing
Answer:
2 7/8
Step-by-step explanation:
first step is making these into improper fractions for example 6 1/8 would equal 49/8 because 6*8=48 and add the 1/8 to get 49/8 then do the same with the 3 1/4 make them into 8ths. so it would be 3 2/8 then 26/8 now subtract 49-26 to get 23/8. now simplify to get 2 7/8
