Answer:
slope = -1
Step-by-step explanation:
y2-y1 divided by x2-x1
3-7= -4
2-(-2) = 4
-4 divided by 4 = -1
Well when you are using a fraction strip, it tells you fractions that are equivalent. To know how to fractions are equivalent, then you have to work it out writing out different sets of fractions and seeing if they are the same.
Answer:
i got 21.146
Step-by-step explanation:
multiply 5.45 x 3.88 and thats the answer. it may need to be rounded.
21.10?
Answer:
y= -1.5x-7 is the equation of the perpendicular line
Here's why:
when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.
