r · 7 ≤ 21 [r multiplied by 7 is less than or equal to 21]
7r ≤ 21
[If you wanted to solve it]
7r ≤ 21 Divide 7 on both sides to get "r" by itself
r ≤ 3

<u>Answer:</u>
The equation is y = 2x - 5
<u>Solution:</u>
Here, x= 3; y= 1
We know the slope of an equation is given by y = mx+c
The value of m which is equal to 3 is given in the question.
Putting the value of m in the slope intercept form we get,
y = 2x+c
To find the The value of c, we substitute the value of x and y from any two given point. Lets take x = 3 and y = 1
Therefore, the slope intercept equation becomes y = 2x - 5
