Write an equation of a line with the given slope and y-intercept.

m =4/5 , b = 2

a)y = 4/5x – 2

b)y = 4/5x + 2

c)y = 5/4x + 2

d)y = 2x + 4/5

In y = mx + b form, the slope is in the m position and the y int is in the b position

y = mx + b
slope(m) = 4/5
y int (b) = 2
now just sub
y = 4/5x + 2

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
