You can take the first point as the origin O(0,0) and the second one (-2,0.5) for easier calculations.
Find the slope, m = (y2 - y1)/(x2 - x1)
= -2-0 / -0.5-0 = 2/0.5 = 4
now take (x,y) = (0,0) and m= 4
use the point slope form
(y - y1) = m(x - x1)
(y - 0) = (4)(x - 0) ......taking (x1,y1) = (0,0)
y = 4x + 0 ...... in the form of y = mx + b
I hope I was helpful:)
Answer:
9
Step-by-step explanation:
f(x) = 2(2)² - 3(2) + 7
f(x) = 8 - 6 + 7
f(x) = 2 + 7
f(x) = 9
Answer:
A variable.
Step-by-step explanation:
In 3x, 3 is constant and x is a variable but together, 3x is a variable.
Answer:
3/12 or 1/4 after simplifying
Step-by-step explanation:
3 chances of getting green because there are 3 green and there is a total of 12 marbles so 3 out of 12, which is equal to one fourth.
