Respuesta :
y = -4x + 4
=================
Using the two-point formula:
- y = mx + b, where m is the slope and b is the y-intercept.
First, calculate the slope:
- m = (y₂ - y₁) / (x₂ - x₁)
m = (28 - 4) / (-6 - 0) = 24 / -6 = -4
Then, substitute one point into the equation to find the y-intercept:
- 4 = -4(0) + b
- b = 4
Therefore, the equation of the line is y = -4x + 4.
Final answer:
To find the equation of a line passing through two points in slope-intercept form, calculate the slope using the given points and then use the point-slope form to derive the equation.
Explanation:
The equation of the line passing through (0,4) and (-6,28) in slope-intercept form:
To find the slope (m), use the formula: m = (y2 - y1) / (x2 - x1). Substituting the given points, m = (28 - 4) / (-6 - 0) = 24 / -6 = -4.
With the slope (m = -4) and using the point-slope form y - y1 = m(x - x1), you can calculate the equation of the line in slope-intercept form as y = -4x + 4.
