Write which ones it classifies as
Answer:
linear
Step-by-step explanation:
Slope-intercept form is y = mx + b.
In this form, m is slope and b is y-intercept.
Slope is rise over run. The formula for this is (y2-y1)/(x2-x1).
Y-intercept is the value of y when x is equal to 0.
1. Slope = 8 ; Y-intercept = 0
y = mx + b
m = 8 ; b = 0
y = 8x + 0
y = 8x
2. Slope = 1 ; Y-intercept = 2
y = mx + b
m = 1 ; b = 2
y = 1x + 2
y = x + 2
The answer to #1 is y = 8x.
The answer to #2 is y = x + 2.
Hope this helps!
Answer:
A
Step-by-step explanation:
50 = x^2 - 9x + 14
x^2 - 9x + 14 - 50 = 0
x^2 - 9x - 36 = 0
(x - 12)(x + 3) = 0
x - 12 = 0
x = 12 <==
x + 3 = 0
x = -3......not this one
