Question

Directions. Answer questions (a – f) based on the following graph.

Answer 1

A. When x = -1, the value of y is equal to 3.

B. When y = 7, the value of x is equal to 1.

C. The y-intercept of the graph is equal to -2.5.

D. The x-intercept of the graph is equal to 5.

E. The slope of the line is equal to -1.75

F. The equation of the line is equal to y = -1.75x - 2.5

What is y-intercept?

In Mathematics, the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

How to calculate the slope and equation of this line?

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

• m represents the slope of a line.
• x and y are the points on a graph.
• c represents the y-intercept.

Making slope (m) the subject of formula, we have the following:

Slope, m = (y - c)/x

Slope, m = (1 - (-2.5))/-2

Slope, m = (1 + 2.5)/-2

Slope, m = -3.5/2

Slope, m = -1.75.

For the equation of this line, we have:

y = mx + c

y = -1.75x - 2.5
