Which is the slope of the line with equation 7x−3y=21?
3/7
-3/7
7/3
-7/3
7x - 3y = 21.
Slope = -A/B = -7/-3 = 7/3.
rearrange it to read
3y = 7x+21
Now what do you think?
it is A/B = -7/-3 = 7/3 that is your answer hope it helps
To find the slope of a line given its equation, you need to rewrite the equation in slope-intercept form, which is y = mx + b. Once you rewrite the equation in this form, the coefficient of x will give you the slope.
Let's rewrite the given equation 7x - 3y = 21 in slope-intercept form:
First, isolate the term with y:
-3y = -7x + 21
Next, divide both sides of the equation by -3 to solve for y:
y = (7/3)x - 7
Comparing this equation to the slope-intercept form, we can see that the coefficient of x is 7/3. Therefore, the slope of the line is 7/3.
So, the correct answer is 7/3.
