Question 647287




The equation to put into y equals in your graphing calculator is: {{{y= 3.50x+20}}}, 
The number attached to {{{x}}} in the equation is always the slope, and {{{y- intercept}}} you will get if you set {{{x=0}}}.
S0, in your case the {{{slope}}} would be {{{3.50}}} and {{{20}}} would be your {{{y- intercept}}}. 

 
If you have to draw the graph by hand remember rise over run, and start with your {{{y- intercept}}} point on the {{{y }}}axis, and {{{x- intercept}}} point on the {{{x }}}axis. 

{{{y- intercept}}} is at ({{{0}}},{{{20}}})

{{{x- intercept}}}
{{{0= 3.50x+20}}}.......->... {{{-20= 3.50x}}} ->... {{{-20/3.50= 3.50x}}}->... {{{-5.7= x}}}........so, {{{x- intercept}}} is at ({{{-5.7}}},{{{0}}})

{{{ graph( 600, 600, -10, 10, -10, 30, 3.50x+20) }}}
