Write the slope-intercept form of the equation with the given characteristics.1. slope = 1/4, y-intercept = 22. slope = -3/2, passes through (-4,7)3. passes through (-2,1) and (2,-5)4. parallel to the line y= -3x+5, passes through (-4,5)5. perpendicular to the line y=1/2x-8, passes through (7,-6) answer because i'm studying for finals along with a bunch of other subjects

1. y=1/4x+2

2. y=-3/2x +1

3. y = -3/2x -2

4. y= -3x -49

5. y = -2x +8

Step-by-step explanation:

1. Use slope intercept, y=mx+b where m =1/4 and b=2. y=1/4x+2

2. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.  

(y-7)=-3/2(x--4)  

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

y-7=-3/2x-6

y = -3/2x -6 +7

y=-3/2x +1

3. To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.  

(y--5)=-3/2(x-2)  

y+5=-3/2(x-2)

y+5=-3/2x + 3

y = -3/2x -2

4. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope is -3 since parallel lines have the same slope.  

(y--4)=-3(x-5)  

y+4=-3 (x+15)

y+4=-3x -45

y= -3x -49

5. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope is -2 since perpendicular lines have the negative reciprocal slopes. So 1/2 becomes -2.

(y--6)=-2(x-7)  

y+6=-2 (x-7)

y+6 = -2x + 14

y = -2x +8

i do not know this sorry : (
