Write the equation of the line passing through (-3,-5) and (3,0)

Use the formula for a slope:
Slope=m=%28%28y1-y2%29%2F%28x1-x2%29%29
Use the formula for a slope:
Slope=m=%28%28-5-0%29%2F%28-3-3%29%29 [plug-in the values (-3,-5) and (3,0)
and solve]
Slope=m=%28%28-5%29%2F%28-6%29%29
Slope=m=%28%285%2F6%29%29
.
Next, use the slope-intercept equation of a line: y=mx+b
y=mx+b [plug-in the values and solve for the b-term]
-5=(5/6)(-3)+b
-5=(-5/2)+b
-5+(5/2)=(-5/2)+(5/2)+b
-5/2=b [plug-in (b=-5/2) and the slope (5/6) into y=mx+b
.
y=mx+b
y=5/6x-5/2
