Answer:
1. y = 2x+3
2. y= -2x-1
3. y=3/5 x +3
4. y = 1/2 x 23/2
Step-by-step explanation:
1. Use slope intercept, y=mx+b where m =2 and b=3. y=2x+3
2. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-5)=-2(x--3)
y-5=-2(x+3)
y=-2x-6+5
y=-2x-1
3. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope is 3/5 since parallel lines have the same slope.
(y-3)=3/5(x-0)
y-3=3/5 x
y=3/5 x +3
4. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope is 1/2 since perpendicular lines have the negative reciprocal slopes. So -2 becomes 1/2.
(y-10)=1/2(x--3)
y-10=1/2 (x+3)
y-10 = 1/2 x + 3/2
y = 1/2 x 23/2

Answer:
6
Step-by-step explanation:
anything over 5 you round up.
7 is greater than 5 so you round up to 6
