You can put this solution on YOUR website! Find an equation of the line passing (-7,2) and (4,5)
Equation of a line: y=mx+b, m=slope, b=y-intercept
For given problem:
m=∆y/∆x=(5-2)/(4-(-7))=3/11
equation: y=3x/11+b
solve for b using one of given coordinates(4,5)
5=3*4/11+b
b=5-12/11
b=55/11-12/11=43/11
equation: y=3x/11+43/11
see graph below:
