Question

In Desmos, type in the points (0.25,0) ( 0, -1) in the graph

What is the y intercept of the graph?

Answer 1

Ans:-

Let the linear equation of the line $y=mx+c$

then

for $(0.25,0)$ $\Rightarrow$ $0=m\times0.25+c$

for$(0,-1)\Rightarrow$ $-1=m\times0+c$

After solving these two equation $m=4$ $c=-1$

the equation of line will be $y=4x-1$

Therefore intercept along y-axis is $-1$
