Complete the slope-intercept form of the linear equation that represents the relationship in the table.
nevsk [136]

According to the given table, the slope-intercept equation of the line is given by:

y = -2x + 1

The equation of a line, in <em>slope-intercept</em> form, is given by:

y = mx + b

In which:

  • The slope is m.
  • The intercept is b.

In this problem, we are given two points, (3,-5) and (-2,5).

  • The slope is given by <u>change in y divided by change in x</u>, hence:

m = \frac{5 - (-5)}{-2 - 3} = -2

Hence:

y = -2x + b

Point (3,-5) means that when x = 3, y = -5, which is used to find b.

y = -2x + b

-5 = -2(3) + b

b = 1

Hence, the equation of the line is:

y = -2x + 1

Alex Ar [27]

Answer:

76

Step-by-step explanation:

n a competitive exam of 40 questions, +3 is awarded for a correct answer and -1 for every wrong answer. Find the total score if a student had 11 wrong answers in his attempt of all questions.

Answers gotten wrong = 11

answers gotten right = 40 - 11 = 29

total score = (point for correct answer x number of correct answer) +  (point for wrong answer x number of wrong answer)

(+3 x 29) + (-1 x 11) = 76
