Astudent is attempting to find an equation for a line that passes through two points. which statement best applies to the mathematical work shown below?

given the points (1, –2) and (2, 3), to find the equation of the line that passes through the two points, i first find the slope. i find that . i then find the y-intercept by , which implies b = 1. therefore, y = x + 1.

a) the student did not use the correct formula to find the slope
b) the student used the correct formula to find the slope, but made a calculation error in determining the actual number
c) the student made a calculation error in finding the y-intercept
d) the mathematical work shown above is correct as written
