Use point slope formula to write an equation of the line given the following information. Write answer in slope intercept form slope -3/4 line passes through point (5,0). Simplify fraction answers.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. The slope m is given as\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28y2-y1%29%2F%28x2-x1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. Let (x1,y1)=(5,0) or x1=2 and y1=1 . Let other point be ((x2,y2)=(x,y) or x2=x and y2=y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Now we're given \"m=-3%2F4\". Substituting above values and variables in the slope equation \r
\n" ); document.write( "\n" ); document.write( "m yields the following steps:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28y2-y1%29%2F%28x2-x1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-3%2F4=%28y-0%29%2F%28x-5%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Multiply x-5 to both sides to get rid of denominator on right side of equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-3%28x-5%29%2F4=y-0\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-3x%2F4%2B15%2F4=y\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=-3x%2F4%2B15%2F4\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Note: the above equation can be rewritten as \r
\n" ); document.write( "\n" ); document.write( "\"3x%2B4y=15\"\r
\n" ); document.write( "\n" ); document.write( "And the graph is shown below which is consistent with the above steps.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"3+x+%2B+4+y+=+15\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-3%2F4\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 15/3 = 5.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 15/4 = 3.75.
  • Slope is -3/4 = -0.75.
  • Equation in slope-intercept form: y=-0.75*x+3.75.
