Answer:
y+1=-3(x-4)
Step-by-step explanation:
first you want to plug in the numbers into the formula which y-y1=m(x-x1).
then you get y+1=-3(x-4)
Answer:176 psychology textbooks and 98 Biology textbooks were sold.
Step-by-step explanation:
Let x represent the number of psychology textbooks that were sold.
Let y represent the number of biology textbooks that were sold.
textbook store sold a combined total of 274 psychology and biology textbooks in a week. This means that
x + y = 274 - - - - - - - - - - -1
The number of psychology textbooks sold was 78 more than the number of biology textbooks sold. This means that
x = y + 78
Substituting x = y + 78 into equation 1, it becomes
y + 78 + y = 274
2y = 274 - 78
2y = 196
y = 98
x = y + 78 = 98 + 78
x = 176
Multiply everything in parenthesis by the 1/6 ,. you get 3x-4
Answer:
y =
Step-by-step explanation:
Let the equation of the line passing through a point (x', y') and slope 'm' is,
y - y' = m(x - x')
Slope of the line passing through and is represented by,
m =
If two points given in the bale are (-9, 10) and (3, 32),
Slope 'm' =
=
=
Therefore, equation of the line passing through (3, 32) and slope = will be,
y - 32 =
y =
y =
