y-y1=m(x-x1)

5

What is Standard Form?

Ax+By=C where A,B,C are integers and A>0

15

What is slope-intercept form?

y=mx+b

15

Write the equation of the line in slope-intercept form that has a slope of -2 and passes through (1,-3)

y=-2x-1

25

Write an equation in Standard Form that has a slope of -4 and y-intercept of 3.

4x+y=3

15

Write the equation in slope-intercept form for the line that passes through (-3,4) and (6,1).

y=-1/3x+3

5

Write the equation of the line in point-slope form that has a slope of -2/3 and passes through (4,-7)

y+7=-2/3(x-4)

10

Point-slope form that goes through (0,4) and (2,-8).

y-4=-6(x-0) or y+8=-6(x-2)
