Question
Write the equation of the line that passes through the points (0, -5) and (4, 3).
- y=2x-5
- y=1/2x-5
- y=2x+5
- y=1/2x+5
Hint:
slope of the line is (m) = 
where ( x2 , y2 ) and ( x1 , y1 ) are points given
now you have slope find intercept by using one point and slope of line .
The correct answer is: y=2x-5
Given points are (0, -5) and (4, 3).
Step1 : slope of the line is (m) =
Slope of line =
=
= 2
Step 2 : Let the y-intercept be b
The slope-intercept form of equation of the line is y=mx+b
Since the line passes through (0, -5), so, the y-intercept of the line is -5
b= -5
So, the equation of the line is y=2x-5
if x = 0 , then the corresponding value of y will be intercept.
