Xints are where y=0

0=x^2+4x-12
0=(x-2)(x+6)

x-2=0
x=2

x+6=0
x=-6

(x,y)
xints are
(2,0) and (-6,0)

Find the y-intercept from the line passing through (1, 3) and having slope m=2.

Troyanec [42]

Answer:

The y intercept is 1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the equation and solve for y

3 = 2(1)+b

3 =2+b

1 = b

The y intercept is 1
