2 8/9
Step-by-step explanation:
Answer:
y = -1/2x + 13/2
Step-by-step explanation:
The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos
I think you guys are using a^2 + b^2 = c^2
the equation would be
x^2 + 2x^2 = 6^2
1) k is 180*-120*=60*
2)M is 180*-40*=140*
