Points: (0, 0) and (7, -t)
Slope: -3/5
Slope = 0--t/0-7 = -3/5
- t/7 = -3/5
Multiply both sides by -7:
t = 21/5 or 4.2

A line passes through the origin and has a slope of?
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
Does the slope of a line through a orgin is always defined?
No. The y axis passes through the origin but its slope is not defined.
What is the slope that passes through the point 2 1 and 2 - 3?
The line is vertical and so the slope is undefined.
What is the equation of a line that passes through the origin and has a slope of -2?
It is: y = -2x
Which is an equation of a line with a slope of 3 that passes through the origin?
y = 3x
What is the equation of a line that has zero slope and passes through the origin?
y = 0. You can get this from the slope-intercept equation of the line.
Which is an equation for the line that passes through the origin and has a slope of 3 over 5?
If you know that the line passes through the point (0,0) and has a slope of 0.6, then you can use the point-slope formula to find the equation of the line. y - y1 = m(x - x1) becomes y - 0 = 0.6(x - 0) becomes y = 0.6x
