What is the slope and y-intercept of (0,8) (1,10) (2,12) (3,14) (4,16) (5,18)
Anna71 [15]
To get slope use

y2 - y1 / x2 - x1

10 - 8 / 1 - 0 = 2/1 = 2

Slope = 2

The y-intercept is the coordinate point that has 0 as the x value.

(0, 8) is the y-intercept.

lara31 [8.8K]

Answer:

C. X= -2.01 and x= 1.67

Step-by-step explanation:

3x {}^{2}  + x + 10 = 0 \\ 3x {}^{2}  + 6x - 5x + 10 = 0 \\ 3x(x + 2) - 5(x + 2) \\ (x + 2)(3x - 5 )\\  x  + 2 = 0 \:  \: or \:  \: 3x - 5 = 0 \\ x =  - 2 \:  \: or \:  \: x =  \frac{5}{3}
