Answer:
-18
Explanation:
Given equation:
![\[y+4=-4(x+3.5)\]](https://img.qammunity.org/2020/formulas/mathematics/college/im2dxo6wr2y2no6tl646dc70a2z1zcxia0.png)
Simplifying:
![\[y+4=-4x-14\]](https://img.qammunity.org/2020/formulas/mathematics/college/67pjc3gbh2pdv4alq9qumgrzoeb88e9vcq.png)
=>
![\[y=-4x-14-4\]](https://img.qammunity.org/2020/formulas/mathematics/college/92fxxxjw8vp0g9wouljit7xx08kaoqshi7.png)
=>
![\[y=-4x-18\]](https://img.qammunity.org/2020/formulas/mathematics/college/ihzfs9pgvyqr22byofcdd2qnlg5hll86f8.png)
This is of the form y=mx+c where m is the slope of the line and c is the y intercept.
So, in this case, slope of the line is -4 and the y-intercept is -18.
This can also be verified by setting x=0 in the equation of the line.
