Answer:
The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7
Step-by-step explanation:
The slope-intercept form of an equation is given by:

here m is the slope of the line and b is the y-intercept
Given

Putting m=2 in the general form

In order to find the y-intercept, the given point (-3,1) will be substituted in the equation
So

Putting the value of b

Hence,
The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7
We will transform the equation to the vertex form:
y = x² + 8 x + 12 = x² + 8 x + 16 - 16 + 12 =
= ( x + 4 )² - 4
Vertex form is: y = a ( x - k )² + h
Vertex coordinates are: ( - 4, - 4 ).
I wanna say standard but I’m sure. Sorry if I’m wrong I’m in precal now. Not algebra
