V=BA×h
A(triangle)=(4×3.5)/2=7cm²
V(prism)=7×10=70cm³
Hope this helped!
We can still use point-slope form on this question (even though others will use the standard form) We plug in the points: (0, -4) and (6, 0)
Remember the format? We can get the slope like this: y1-y2/x1=x2
Them we get -4-0/0-6 = -4/-6= 4/6=2/3
So 2/3 is the slope, and the y-int is -4
so we get y=2/3x-4
The answer is 12. Hope this helps!
