Question

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 (StartFraction negative 3 Over 10 EndFraction, 5). The student’s work is shown to the left.
Analyze the steps to identify the error.
a. Step1: student switched the x and y values
b. Step 3: student needed to add StartFraction 6 Over 10 EndFraction to both sides
c. Step 5: student subtracted incorrectly
d. Step 6: student needed to add the b value

Answer 1

Answer:

Step-by-step explanation:

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 (StartFraction negative 3 Over 10 EndFraction, 5). The student’s work is shown to the left.'

y = mx +b

STEP 1 WAS CORRECT

STEP 2 WAS CORRECT

STEP 3 WAS CORRECT

STEP 4 WAS CORRECT

STEP 5 WAS CORRECT

STEP 6 IS INCORRECT  THE STUDENT PUT -B NOT B
