What is an equation of the line that passes through the points (7, 6) and (-2, -3)?

Remember the formula for the slope which is change in y over change in x

therefore:      (7+2)/(6+3)= 1         slope=1

formula for a line is y=mx+b

plug in your slope and one of the given coordinates to find the y-intercept:

y=1x+b

7=1(6)+b

7=6+b

1=b

so the equation for the line would be y=x+1

i belive those are the ones that are under 90 degreese.
