Step-by-step explanation:
A linear line is a straight line. It can be going up, down, vertical, or horizontal. As long as it's a straight line, then it is a linear equation. Graph 1 and 5 are linear.
A quadratic graph is a parabola. It is in the shape of a "U". The "U" can be doing up or down. It can also be more than a parabola. Any x to th epower of a number is also a quadratic graph. Graph 2 and 4 are quadratic graphs.
An exponential graph is a graph that is a number to the power of x. These graphs are also continuous. They go towards infinity. Graph 3 and 6 are exponential.
equation of line passing through (1,-7)( -4,8)
First let's find slope (m)
m = (8+7)/(-4-1)
= 15/-5 = -3
(x1,y1) = (1,-7)
Plugging above value in
y - y1 = m( x-x1)
y+7 = -3( x-1)
y+7 = -3x +3
y+3x +4=0
