Question

the equation of the straight line with the gradient -2 and y-intercept 4 is:

Answer 1

Step-by-step explanation:

We know that the equation of a line is y=mx+c where m is the slope of the line and c is the y-intercept.

Therefore, with slope m=2 and y-intercept c=−4, the equation of a line is:

y=mx+c

⇒y=(2×x)+(−4)

⇒y=2x−4

⇒2x−y−4=0

Hence, the equation of a line is 2x−y−4=0.
