Answer:
-7/3
Step-by-step explanation:
6d + 8 = 3d + 1 (subtract 3d from both sides)
3d + 8 = 1 (now subtract 8 from both sides)
3d = -7 (divide both sides by 3)
d = -7/3

Answer:
y +2 = (1/4)(x +1)
Step-by-step explanation:
The given line is in slope-intercept form:
y = mx + b
where the slope (m) is -4 and the y-intercept (b) is +13.
For the perpendicular line, we need a slope that is the opposite reciprocal, or ...
-1/m = -1/(-4) = 1/4
A suitable form for the desired equation is the point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...
y +2 = (1/4)(x +1)
Start at (0,-2) where the graph crosses the y axis.
Move down 1 unit. Then move to the right 4 units. You should arrive at the point (4,-3)
This means the slope is -1/4. Note how
slope = rise/run = -1/4
rise = -1 (amount we go up or down)
run = 4 (amount we go to the right)
The negative rise value indicates we went down instead of up.
