Answer 1

The equation is:

y=54x−13

Step-by-step explanation:

The slope-intercept form of a straight line is

y=mx+c

In this case we have a point,

(x,y)

and the slope,

m

so all we need is a value for

c

.

Substitute into

y=mx+c−3=54(8)+c−3=10+cc=−13

The equation is: y=54x−13

Or you can use the formula for the situation where you have a point,

(x1,y1)

and the slope, (m)

→

y−y1=m(x−x1)y−(−3)=54(x−8)y+3=54x−10y=54x−13

Answer 2

Step-by-step explanation:

Given data

line points (8,9)

slope=4

RTF equation

y-y1=m(x-x1)

y-9=4(x-8)

y-9=4x-32

y=4×-32+9

y= 4x-23
