Question

Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form.

Y=3x-7
Y=3x-5
Y=5x-11
Y=5x-9

Answer 1

To find the slope, you use the slope formula.
y2-y1/x2-x1
So it would be -1-4/2-3 = -5/-1
The slope is 5.
Then you use the point slope formula, which is y-y1=m(x-x1) .
So it would be y-4=5(x-3)
Then you distribute and get y-4=5x-15
Add a 4 to each side and you get y=5x-11
So the answer is y=5x-11
