Answer:
B
The correct answer would be x=-2
Jason is ignoring the fact that the line going throught these two points is going to form a slope, so he cannot simply subtract those two values. He must either use the distance formula or make a right triangle from the two points to find the length using the Pythagorean theorem.
The required equation of a line is y = -3x- 1
<h3>Equation of a line</h3>
The equation of a line in slope-intercept form is expressed as:
y = mx + b
where
m is the slope
b is the y-intercept
Using the coordinate point (0, -1) and (-1, 2)
Slope = 2-(-1)/-1-0
Slope = 3/-1
Slope =-3
Since the line crosses the y-axis at (0, -1), hence the value of b is -1
Determine the equation
y = mx + b
y = -3x + (-1)
y = -3x- 1
Hence the required equation of a line is y = -3x- 1
