$(0, 5), (5/2, 0)$

$x = 0 \Rightarrow y = -2 * 0 + 5$

$y = 0 \Rightarrow 0 = -2x + 5 \Rightarrow (0 - 5) / (-2) = x$

(a). 5

(b). 5/2

$y=-2x+5$

A straight line graph is of the form:

$y=mx+c$

$m$ = the gradient

$c$ = the intercept which cuts the y axis

You can get this by setting $x$ = 0

So $y=-2xx0+5=5$

So $c=5$ which is the $y$ intercept.

We can get the $x$ intercept by setting $y=0$ :

$0=-2x+5$

$2x=5$

$x=5/2$
