Find the equation of a line which is form origin and passes through the point (−3, −4)
y = 3x4
y = 4x3
y = 2x3
y = x2
Correct answer is B
The slope of the line from (0, 0) passing through (-3, -4) = −4−0−3−0
= 43
Equation of a line is given as y=mx+b, where m = slope and b = intercept.
To get the value of b, we use a point on the line, say (0, 0).
y=43x+b
0=43(0)+b
b=0
The equation of the line is y=43x
