Which answer is the slope of of the line with equation 5x+y=15

1 answer:

4 0

This line is given to us in standard form, $Ax+By=C$ , but it's easiest to see the slope when we convert to slope-intercept form $y=mx+b$ , where m is the slope.

We are going to solve for y.

$5x+y=15\\5x-5x+y=-5x+15\\y=-5x+15\\m=-5$

The slope is the coefficient of the x-term, –5.

we can divide the composite shape into on quadrilateral and triangle as shown in the diagram. since the line that joins the two shape is parallel to the base AB, the angle DEC is 85°.The angle CEA is 180°- angle DEC = 180-85=95. Angle BCE is sum of angle CEA, ABC and EAB subtracted from360°= 360°-(95+95+85)=85°. Angle DCE is 120°- ECB=35°. So, angle CDE = 180°-(35°+85°)= 60°. For reference see the diagram.
