Answer: y = + 30/11
Step-by-step explanation:
Two line are said to be perpendicular to each other if the slope of the first line = -1 / the slope of the second line , that is
If the slope of the first line is M1 and the slope of the second line is M2 , then M1 = -1 / M2.
From the equation given , M1 = - 11 , that means M2 = 1 / 11
Using the formula y - y1 = m ( x - x1) to calculate the equation , we have
y - 3 = 1/11 ( x - 3)
Multiply through by 11 , we have
11 ( y - 3 ) = x - 3
11y - 33 = x - 3
11y = x + 30
y = x/11 + 30/11
Answer:
<h2>y = -35x + 105</h2>Step-by-step explanation:
The given graph represents a function between hours and miles.
To determine the equation that belong to this graph, first we need to find the slope using two points from the graph: (0, 105) and (3, 0).
The definition of slope is
Notice that the slope is -35. Remember that the slope is always the coefficient of variable . So, the choice that has this slope is the right answer.
Therefore, the right answer is the last choice: y = -35x + 105
