Y = -0.5x - 1
Slope = Y2-Y1/X2-X1
Slope = -1.5-(-1)/1-0 = -0.5
Y-in. = X = 0
Y-in. = -1
A number's absolute value means the distance from 0. -6 is 6 units away from 0 units. The absolute value of -6, then, is 6. There's no negative distance you can have, so it has to be positive.
(0,2)(4,6)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (6-2) / (4-0) = 4/4 = 1
y = mx + b
slope(m) = 1
(0,2)...x = 0 and y = 2
now we sub
2 = 1(0) + b
2 = b
so ur equation is : y = x + 2
