The point (7, 8) is the solution of which of the following systems of equations?
Alex73 [517]

Option 4

<u>V</u><u>e</u><u>r</u><u>i</u><u>f</u><u>i</u><u>c</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u>

\\ \sf\longmapsto x-7y=-49

\\ \sf\longmapsto 7-7(8)=-49

\\ \sf\longmapsto 7-56=-49

\\ \sf\longmapsto -49=-49

And

\\ \sf\longmapsto 10x+9y=142

\\ \sf\longmapsto 10(7)+9(8)=142

\\ \sf\longmapsto 70+72=142

\\ \sf\longmapsto 142+142

Hence verified

1) A line with gradient 2 passes through (0, 4). Write down the equation of the line.
blondinia [14]

<em>For</em><em> </em><em>the</em><em> </em><em>attached</em><em> </em><em>image</em><em>,</em><em> </em><em>note</em><em> </em><em>that</em><em> </em><em>slope</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>thing</em><em> </em><em>as</em><em> </em><em>gradient</em><em>.</em>

1) y = 2x + 4

2) Substituting in x = 1 and y = 1,

1 = 4(1) + c

1 = 4 + c

c = -3

So, the equation is y = 4x - 3
