since this is a graded assignment to be handed in, i will not do the problem for you. i will rather give you the method, or hints on how to solve the problems.

you may want to search the forum for something like "equation of a line," there are many problems of this nature that has been done here.

the slope intercept form of a line is: where is the slope, and is the y-intercept

here's how to get that equation given two points on a line.

we first find the slope:

recall that the slope is rise over run, that is, change in y divided by the change in x. so given two points on a line, and , we find the slope, m, as follows:

we then use the point-slope form:

use either of the points given and the slope you found, and plug them into the slope-intercept form shown below:

where is the point you used, and m is the slope

finally, solve for y:

solving for y in the above form and simplifying will give you the slope-intercept form of the equation of the line
