A student used the slope-intercept form to write the
equation of a line that has a slope of -2 and passes
through the point (-10,5). The student's work is
shown to the left.
Analyze the steps to identify the error.
O Step1: student switched the x and y values
Step 3: student needed to add to to both sides
Step 5: student subtracted incorrectly
O
Step 6: student needed to add the b value

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
