Think about the process find the expression that will correctly find the slope of a line that goes through the points (-4,0) and (4,2). find the slope of the line.

which of the following expressions will correctly find the slope of the line?
a. 0-2/4 - (-4)
b. 0 - (-4)/2 - 4
c. 2-0/-4 - 4
d. 2 - 0/ 4 - (-4)

3-12. write each answer with a reasonable number of figures. find the absolute uncertainty and percent relative uncertainty for each answer. (a) [12.41 (±0.09) + 4.16 (±0.01)] x 7.068 2 (±0.000 4) =? (b) [3.26 (±0.10) x 8.47 (±0.05)] - 0.18 (±0.06) =? (c) 6.843 (±0.008) x 104 + [2.09 (±0.04)- 1.63 (±0.01)] =?

In the 30-60-90 triangle below side s has a length of and side r has a length

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 8 = -6x a. –7.12, 1.12 b. 7.12, –1.12 c. 7.12, 1.12 d. –7.12, –1.12
