Answer: <em>$20.56</em>
Step-by-step explanation:
<em>Let's take our given total and use this equation</em>
<em>25.70(n)</em>
<em>n will equal 0.80 in this case, as they left a 20% tip so we need to find out what 80% of 25.70 is first</em>
<em /><em />
<em>$20.56 is the total without the tip!</em>
Answer:
Point-slope form of equation given as .
Slope-intercept form of equation is given as .
Step-by-step explanation:
In the question, it is given that the slope of a line is -2 and it passes from (-2,2).
It is asked to write the point-slope form of the equation and rewrite it as slope-intercept form.
To do so, first find the values which are given in the question and put it in the formula of point-slope form. Simplify the equation to rewrite as slope-intercept form.
Step 1 of 2
Passing point of the line is (-2,2).
Hence, and
Also, the slope of the line is -2.
Hence, m=-2
Substitute the above values in point-slope form of equation given by
Hence, point-slope form of equation given as y-2=-2(x+2).
Step 2 of 2
Solve y-2=-2(x+2) to write it as slope-intercept form given by y=mx+c.
Hence, slope-intercept form of equation is given as y=-2x-2.
