Step-by-step explanation:
90+75=135
135-125
Answer:
147
Step-by-step explanation:
Since it says need to use 3 to represent pi
well show the formula.
The radius is 7 so we square it, and do the formula.
A=3r²
A=3*49
A=147
Answer:
(a) Slope and y-intercept; (b) y = mx; (c) y = x + b
Step-by-step explanation:
1. Need to know
Slope and y-intercept.
You use these numbers to calculate one other point. Then you draw a straight line between the y-intercept and the other point to get the graph.
2. y-Intercept = 0
The form of the equation is y = mx + b, where b is the y-intercept.
If the intercept is zero, b = 0, and the equation has the form
y = mx
The graph is a straight line passing through the origin.
3. Slope = 1
m represents the slope. If m = 1, the equation has the form
y = x + b
If the axes are scaled equally, the graph is a straight line that crosses the y-intercept at an angle of 45°.
Quick answer A <<<<
All horizontal lines have an equation of
y = k where k is a number. k is the y intercept.
Here are a few lines drawn for you.
y = 3
y = 1
y = - 1
y = - 2
In y = ax + b the term ax disappeared. The graph shows that x is not zero. It has many values. So the m must be zero.
