Identify an equation in point-slope form for the line perpendicular to y =3/4x -4 that passes through (-1, 7).

y - 7 = -4/3(x + 1)

Step-by-step explanation:

Given

Convert to point slope form

y - y1 = m(x - x1)

m: represents what the slope is

y - 7 = -4/3(x + 1)

Distribute -4/3

-4/3 * x = -4/3x

-4/3 * 1 = -4/3

y - 7 = -4/3x - 4/3

Add seven in both sides

21/3 -4/3 = 17/3

y = -4/3x + 17/2

Answer

linear equation: y = -4/3x + 17/2

point-slope form: y - 7 = -4/3(x + 1)

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
