which of the following is not a step used when graphing the equation y = −x + 8 using the slope-intercept method? Plot the x-intercept (32, 0). Plot the y-intercept (0, 8). Draw a line through the two points. Count down 1 and right 4 from the y-intercept.

OpenStudy (anonymous):

The first step. The x-intercept is when Y = 0. Thus, 0= -x +8 or x=8. The x int is 8,0 not 32,0. The last step is also wrong. The slope of the line is -1. Thus, down 1, right 1 from the y-intercept.

So does this mean the answer is C ? ....

OpenStudy (anonymous):

If C, states that the first and last step are incorrect, yes.

clearly there is a typoe in the equation. however we can answer this question, as slop-intercept method doesnt require x-intercept to be plotted. so your answer is A
