Question 450803
Write an equation in slope-intercept form for each line described. 
A)Slope= 8 passes through (-7,5) 
B)Vertical and passes through (-4,-2)
..
A)Slope= 8 passes through (-7,5)
Standard form of equation: y=mx+b
For given equation: y=8x+b
solve for b using given point on curve (-7,5)
5=8*-7+b
b=5+56=61
Equation of given line: y=8x+61
See graph below for a visual of given straight line equation.

..
B)Vertical and passes through (-4,-2)
A vertical slope means that the equation becomes: x=-4, (y does not matter)
