1.the line with the slope of -8 and a y-intercept of 3 (in slope-intercept form) 

2.the line that passes through (-2,0)and has a slope of 5 (in point-slope form) 

3.the horizontal line that passes through (-2,6) 

4.the vertical line that passes through (-2,6) 

Ans:

1)

Equation of a line with slope m and y-intercept c is given by y = m*x + c

Here slope = -8, y-intercept = 3

So eqn is  or 

2)

Eqn of a line that passes through x1,y1 and has slope m is given by



Here, (x1,y1) = (-2,0) and slope = 5



 or  is the equation

3)

Horizontal line has the equation of the form y = 

Since it passes through (-2,6), one value of y, which is the constant value,

has to be 6.

So, the equation is 

4)

Vertical line has the equation of the form x = 

Since it passes through (-2,6), one value of x, which is the constant value,

has to be -2.

So, the equation is  or 



Hope you got it :)
