Explanation: The equation of the line in slope-intercept form has the following general formula: y = mx + c where: m is the slope of the line = 8 c is the y-intercept = 7
Substitute with the givens in the above formula to get the slope of the line as follows: y = mx + c y = 8x + 7
easy 230-80 which is 150 so imagine a triangle with base 150 and hight 130-60=70 so times for area 150×70÷2 because it's triangle which is <em>5</em><em>2</em><em>5</em><em>0</em> so plus that with 130x80 for rectangle which is 10400 and add so it's 15650
