Answer:
The correct answer is B) y = 2x - 1
Step-by-step explanation:
To find this, first choose any two data points and find the slope. We'll use points (-2, -3) and (0, 1)
m(slope) = (y2 - y1)/(x2 -x1)
m = (1 - -3)/(0 - -2)
m = 4/2
m = 2
Now we use either point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = 2(x - 0)
y - 1 = 2x
y = 2x + 1
Answer:
THE ANSWER IS NO
Step-by-step explanation:
Positive 8 and negative 8 both are.
Answer:
y = 2x + 4
Step-by-step explanation:
Two points on this line are (-2, 0) and (0, 4). Going from the first to the second, x increases by 2 (this is the 'run') and y increases by 4 ('rise').
Thus, the slope of this line is m = rise / run = 4/2 = 2
Using the slope-intercept formula, we get y = mx + b = 2x + b
Let x = -2 and y = 0 to find b: 0 = 2(-2) + b, so b = 4, and the desired equation is then:
y = 2x + 4
