Answer:
y-4=-7(x-1) OR y-(-10)=-7(x-3)
Step-by-step explanation: The point-slope form is -
=
(
-
)
In slope-intercept form, the equation would be y = -7x + 11
You could find the slope by using the slope equation, .
Using that, you would get -7. Thus by inserting one of the points and the slope in the point-slope equation, you will get your answer.
Let's pick two points on the line, the y-intercept, and the x-intercept. These are the points at which x=0, and y=0.
When x=0:
So one point is (0,6)
When y=0:
So another point is (10,0)
So mark the points (0,6) and (10,0) on a pair of axes, and draw a straight line between them, and past them to infinity. This is a graphing of the line y=-3/5 x + 6
