Answer:
1=2(4)+b
Step-by-step explanation:
slope intercept looks like this y=mx(or y=#x+#
if the slope is 2 the equation will be y=2x+b
to find b so x=4 and y=1 we can plug those numbers into the equation to find b
-3 + 8i is in quadrant II
4i is on the vertical axis
6 is on the horizontal axis
5 - 2i is in the quadrant IV
Answer:
16.3°
Step-by-step explanation:
Cos x = adjacent side/hypotenuse
= 24/25
x = arccos (24/25) = 16.3°
You must memorize the definitions of the trig functions and then this type of problem is easy. OK?
2nd and 3rd option looks correct. 1st option is not true and I am pretty sure 4th one is not true as well
Answer:
Point Slope: (y + 1) = 2x
Slope Intercept: y = 2x - 1
Step-by-step explanation:
I'll do it in two forms.
Slope = (3 + 1) / (2 - 0) = 2
Point - Slope: (y + 1) = 2x
Slope Intercept: y = 2x + b
-1 = b
y = 2x - 1
