Answer:
b. y-y1 = m(x-x1)
Step-by-step explanation:
It's a matter of definition. There are perhaps a dozen useful forms of equations for a line. Each has its own name (and use). Here are some of them.
- slope-intercept form: y = mx + b
- point-slope form: y -y1 = m(x -x1)
- two-point form: y = (y2-y1)/(x2-x1)(x -x1) +y1
- intercept form: x/a +y/b = 1
- standard form: ax +by = c
- general form: ax +by +c = 0
Adding y1 to the point-slope form puts it in an alternate form that is useful for getting to slope-intercept form faster: y = m(x -x1) +y1. I use this when asked to write the equation of a line with given slope through a point, with the result in slope-intercept form.
Answer: the answer is 0.078, 0. 708, 0.78, 0.87
Moses: God told Moses to go back to Egypt and demand the Israelites be released. He then led the Israelites across the red sea and settled on Mount Sinai and received the ten commandments. Moses died before making it to the promised land
Answer: y=6
Explanation: If you put the equation y=6 into graph form (as seen in the picture below) you will have a horizontal line that goes through the point (9,6)
(P.S the black dot represents the point (9,6))
