**So we can find out the equation of the line if we know the slope and the x intercept along with its sign(positive or negative). If we don't know the sign of x intercept, there will be 2 possible solutions to the problem.**

Hi,

I wanted to double check my answer before I turned in this assignment. I answered this question as follows: No, because in order to find the equation of a line you must be given not only the slope, but also the point on a line, which includes the y-intercept. Is my answer correct/justifiable?

Any help is appreciated!

Tutors, sign in to answer this question.

Hi Rachel,

Equation of a line can be written by y = mx + c where m is slope and c is intercept on y axis.

Now in the question we are given the slope and x intercept ( I am assuming we know whether the intercept is positive or negative). The y coordinate will be zero for the point where the line cuts x axis.

Just for example it is given the slope of line is 4 and x intercept is +1.

Now using this information and the basic line equation we have,

0 = 4*1+c

c = -4

Therefore equation of line will be y= 4x-4
