Complete the equation for the linear function whose graph contains the points (7,8) and has a slope of -1.2.
1 answer:
Y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value and 'm' is the slope.
y - 8 = -1.2(x - 7)
Distribute -1.2 into the parenthesis:
y - 8 = -1.2x + 8.4
Add 8 to both sides:
y = -1.2x + 16.4
