The slope of the first equation has a slope of one and a y intercept of -4. The second equation has a y intercept of -2.3333 as seen when plugging in 0 for x, so the same y-intercept and same line are out of the question. This means either they have the same slope and thus are parallel or intersect at some point. A simple way to find out? Plug in 1 for x on the second. If it isn't -1.33333, which is a slope of positive 1 such as in the first equation, they WILL INTERSECT somewhere. When plugging in 1, we get
3y - 1 = -7
3y = -6
y = -2
(1, -2) is the next point after (0, -2.3333)
That means it is most certainly not the same slope, and thus they will intersect at some point. The two slopes are 1/1 and 1/3 if you weren't aware.
Answer:
1.1726.
Step-by-step explanation:
Use the identity sec^2 O = 1 + tan^2 O
sec^2 O = 1 + 3/8 = 1.375
sec O = √(1.375)
= 1.1726.
Answer:
false
Step-by-step explanation:
Assuming that says "y-axis", the slope of any line going straight up and down has a slope of 0 and is defined by its x value (i.e. x = -1)
