Question
Change the following equation of a line into slope-intercept form.𝑥=(𝑦−21)7Group of answer choicesy = -7x + 21𝑦=17𝑥+3y = 7x - 21𝑦=17𝑥−3y = 7x + 21
Solution
The given equation is 𝑥=(𝑦−21)/7.
To convert this into slope-intercept form (y = mx + b), we need to solve for y.
First, multiply both sides by 7 to get rid of the denominator on the right side:
7x = y - 21
Then, add 21 to both sides to solve for y:
y = 7x + 21
So, the equation of the line in slope-intercept form is y = 7x + 21.
