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
<h3>What is y-intercept?</h3>
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).
<h3>How to calculate the slope and equation of this line?</h3>
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
