Answer:
C.
Step-by-step explanation:
To find the area of a triangle, one must multiply the base by the height then divide by 2.
So, the area of this triangle would be 7.5
Answer: you’re multiplying by 2 each time
I did this on a calculator may or may not be correct but I got 18
Answer:
y=4x-1
Step-by-step explanation:
Slope-intercept form is written in y=mx+b
*m=slope
*b=y-intercept
From what I see,
the line hits the points (0,-1) and (1,3)
Slope is the rise (change in the y-coordinate) of the line divided by the run (change in the x-coordinate).
4÷1=4
Slope=4
y=4x+b now
The y-intercept is the value of y when the line meets the y-axis
It seems to meet at (0,-1)
So we end up with...
y=4x-1 as our equation
