Answer:

y = 13x - 2

the graph is a straight line...TRUE

the line passes thru the origin (0,0)....FALSE

the line passes thru the points (0,-2)...TRUE

the slope of the line is 3...FALSE...the slope is 13

the y int of the line is 2....FALSE...the y int is -2

What is the equation of the line? Write in standard form. (4,5).
dezoksy [38]

Answer:

\large\boxed{5x+4y=20}

Step-by-step explanation:

The equation of a line in slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

We have the x-intercept = 4 → (4, 0), and y-intercept = 5 → b = 5.

Therefore we have the equation:

y=mx+5

Put the coordinates of x-intercept to the equation:

0=4m+5          <em>subtract 4m from both sides</em>

-4m=5           <em>divide both sides by (-4)</em>

m=-\dfrac{5}{4}

Finally we have the equation of a line if slope-intercept form:

y=-\dfrac{5}{4}x+5

The standard form:

Ax+By=C

Convert:

y=-\dfrac{5}{4}x+5             <em>multiply both sides by 4</em>

4y=-5x+20               <em>add 5x to both sides</em>

5x+4y=20
