Answer: \dfrac{-3}{8}

Step-by-step explanation:

The general equation of a line in intercept form is given by :-

y=mx+c, where m is the slope of line and c represents the y-intercept of the line.

The given equation : 8y = 4 - 3x

Divide 8 on both the sides , we get

y = \dfrac{1}{2} -\dfrac{3}{8}x\\\\\Rightarrow\ y=-\dfrac{3}{8}x+ \dfrac{1}{2}

We can see that, the slope of the line : m=\dfrac{-3}{8}

Which linear function represents the line given by the point-slope equation y-8=
Nina [5.8K]

Answer:

f(x)=x+4

Step-by-step explanation:

we have

y-8=(x-4)

This is the equation of the line in point slope form

where

The slope is m=1

The point is (4,8)

Convert to slope intercept form

Isolate the variable y

Adds 8 both sides

y-8+8=x-4+8

Combine like terms

y=x+4

Convert to function notation

f(x)=x+4

Neko [114]

Answer:

Wilson is 6 older than mary

w=6+m

wilson is 10 less than 5 times mary

w=-10+5m

w=5m-10

so now we set them eqal to each other since both equal w

m+6=w=5m-10

m+6=5m-10

minus m both sides

6=4m-10

add 10 to both sides

16=4m

divide both sides by 4

4=m

sub back

w=m+6

w=4+6

w=10

wilson=10

mary=4

the correct method is math
