Answer:
-1/4x + 1 ( If this is wrong then ignore this)
Step-by-step explanation:
The formula for a problem like this is y - y1 = m(x - x1). The x coordinate, -8 is the x1 and the y coordinate 3 is x1. So the equation is y - 3 = -1/4(x + 8)
Equation:
y - 3 = -1/4(x + 8)
y - 3= -1/4x - 2
y = -1/4x + 1
Therefore the equation for the line is y = -1/4x + 1
Answer:
The equation of the line would be y = .5x + 2.5
Step-by-step explanation:
In order to find this, we must first find the slope of the equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (2 - 3)/(-1 - 1)
m = -1/-2
m = .5
Now that we have the slope, we can use either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 3 = .5(x - 1)
y - 3 = .5x - .5
y = .5x + 2.5
Answer:
x = -4/5
Step-by-step explanation:
(5x - 2)2 = 10
2(5x - 2) = 10
2 * 5x = 10x
2 * -2 = -4
5x - 4 = 10x
+4 +4
5x = 10x + 4
-10x -10x
-5x = 4
