The given equation is,

It can be rewritten in the form of y=mx+c, where c is the y intercept.
Hence,

Put different values for x and find value of y.
When x=0, y=1.
When x=1,

The graph is,
29°
triangles can only have 180°
This is a right triangle, so one angle is 90°, leaving us with 90° left
90°-61°= 29°
Answer:
2/8
Step-by-step explanation:
because there are 2 blue marbles
add those up with the red marbles(6) and you get 8 marbles. But the chance for picking up a blue marble would be 2/8
D = {16, 19, 21}
E = {16, 18, 19, 20}
D ∩ E = {16, 19}
