Answer:
y - intercept. = 2.
Step-by-step explanation:
Given : The equation of a line is 5x − 3y = 6.
To find : Which is the y-intercept of the line.
Solution : We have given 5x − 3y = 6.
Equation of line y = mx +b
Where , m = slope , y intercept = b
Now we convert the 5x − 3y = 6 in line form y = mx +b
5x − 3y = 6
On subtracting both sides by 5x
-3x = - 5x + 6
On dividing both sides by - 3.
x = 
.
We cans see m = 
, y - intercept. = 2.
Therefore, y - intercept. = 2.

Answer:
Step-by-step explanation:
Given,
Vertex (h, k ) = (1,0)
Now,
We know,
f(x) = a(x-h)²+k
Since, it passess through (2, −17)
Put x = 2 and y = - 17
or, -17 = a(2 - 1)² + 0
or, -17 = a
Now,
f(x) = a(x - h)² + k
= -17(x - 1)² + 0
= -17x² + 34x - 17
