Answer: C is the correct option
Step-by-step explanation:
The given graphs are straight line graphs.
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
The given equation is
- 5y = - 6x + 15
Rearranging the equation so that it will look like y = mx + c, it becomes
y = 6x/5 -3
The slope, m = 6/5
Looking at the graphs, the slope of graph c is 6/5. This is determined by picking corresponding points
(y2 - y1)/(x2-x1) = (3 - - 3)/(5 - 0) = 6/5
How I learned it was since the X values for the 3 triangles are "-2,-8, and 1", they will simply just subtract 2 from them because it says in the rule "x-2". For the Y values you will simply just subtract 16 from all of them. You may also get questions involving translating it across a line.
4 miles
divide 3 by 70 which is .04 every minute multiplied by 100 which equals 4
Answer:
1.6, but can be rounded to 2
Step-by-step explanation:
You first use the Y intercept to know the y value is 3 when the x values is zero. The rest of the information can be identified if in between each increase in the x term, there was a decrease in the Y term by 4 units
