A line has a slope of 1/4 and passes through point (0.4,-1/2) . What is the value of the y-intercept? –0.6 –0.4 0.275 0.525
I HAVE 30 MINUTES PLEASE

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)] =?

X-intercept=-5 y-intercept=2 the equation of the line is

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
